Laboratory Experiments on the Electrochemical Remediation of the Environment. Part 8. Microscale Simultaneous Photocatalysis Jorge G. Ibanez, Rodrigo Mena-Brito, and Arturo Fregoso-Infante In this article we describe a microscale experiment in which the simultaneous oxidation of an organic compound (citric acid) and the reduction of a metal ion (Cu2+) are photocatalytically performed in an aqueous slurry containing TiO2 irradiated with UV light. This produces electrons (capable of reducing the metal ions) and holes (capable of oxidizing the organic molecule) that can be used for environmental clean up. The experiment allows students to have a better comprehension of the different phenomena involved in a typical photocatalytic process. Ibanez, Jorge G.; Mena-Brito, Rodrigo; Fregoso-Infante, Arturo.

"It Gets Me to the Product": How Students Propose Organic Mechanisms Gautam Bhattacharyya and George M. Bodner Because practicing organic chemists use the arrow-pushing formalism in situations that are far removed from the simple contexts in which they are first presented, this study probed how students enrolled in a first-semester, graduate-level organic chemistry course approached the task of writing the mechanisms for two- to four-step reactions that lacked the typical cues that bring common mechanisms to mind. This article focuses on the students' solutions and discusses possible limitations of their strategies. Bhattacharyya, Gautam; Bodner, George M. J. Chem. Educ. 2005, 82, 1402.

Conversion of an Aziridine to an Oxazolidinone Using a Salt and Carbon Dioxide in Water Justin R. Wallace, Deborah L. Lieberman, Matthew T. Hancock, and Allan R. Pinhas An undergraduate laboratory experiment that allows for optimization of experimental reaction conditions for the conversion of a readily-available aziridine to the corresponding oxazolidinone using only carbon dioxide and a salt in water is discussed. A variety of salts were used to determine their effect on the reaction. In all cases, either no reaction occurred or a high yield of product was obtained. Ring opening of the less substituted carbonnitrogen bond predominates. This experiment allows students to optimize reaction conditions to obtain predominantly one of two regioisomers.

Generation, Isolation, and Characterization of a Stable Enol from Grignard Addition to a Bis-Ester. A Microscale Experiment for the Undergraduate Organic Chemistry Laboratory Olivier J.-C. Nicaise, Kyle F. Ostrom, and Brent J. Dalke A microscale experiment for the undergraduate organic chemistry laboratory that consists of preparing and characterizing an alpha-ketoester and its corresponding, remarkably stable enol form, has been developed. The reaction is that of a Grignard reagent with a bis-ester. A difference in reaction temperature is responsible for the selective generation of the alpha-ketoester and the enol ester. Analysis of spectral data (1H NMR and IR) and a knowledge of organic reactions allows the students to determine the detailed structure of the two reaction products and also to suggest a mechanism for their formation. This experiment introduces students to the concept of stability of the tetrahedral intermediate in acyl-transfer reactions. It also gives them a taste of the unexpected.

The Ethylene Ketal Protecting Group Revisited: The Synthesis of 4-Hydroxy-4,4-diphenyl-2-butanone Marsha R. Baar, Charles E. Russell, and Kristin L. Wustholz The multistep synthesis of 4-hydroxy-4,4-diphenyl-2-butanone from ethyl acetoacetate illustrates the use of a ketal protecting group. Reaction of ethyl acetoacetate with ethylene glycol with p-TsOH in toluene produced the ketal ester. Reaction of the crude ketal ester with two equivalents of phenyl magnesium bromide followed by an aqueous acid workup generated the tertiary alcohol and simultaneously removed the ketal protecting group to produce the hydroxyketone. Our procedure is a modification of a previously published synthesis whose end product was 4,4-diphenyl-3-buten-2-one, the dehydrated analog. Baar, Marsha R.; Russell, Charles E.; Wustholz, Kristin L.

Circular Dichroism Investigation of Dess–Martin Periodinane Oxidation in the Organic Chemistry Laboratory Nicole A. Reed, Robert D. Rapp, Christian S. Hamann, and Pamela G. Artz Using circular dichroism, organic laboratory students investigated the change in absolute stereochemistry upon oxidation of menthol to menthone. In the first laboratory period, the oxidation was performed with DessMartin periodinane, which is a facile and less toxic oxidizing agent. Half the laboratory group performed the oxidation with ()-menthol and the other half used (+)-menthol to produce ()-menthone and (+)-menthone, respectively. The products were analyzed in the second laboratory period using infrared spectroscopy and gas chromatography/mass spectrometry to determine the fraction of starting alcohol converted to ketone. Comparison was made between CD spectra both for the menthol reactant and menthone product and for the (+)- and ()-menthone enantiomers.

The Addition of Bromine to 1,2-Diphenylethene Judith C. Amburgey-Peters and LeRoy W. Haynes We investigated the reaction of (Z)-1,2-diphenylethene (cis-stilbene) with various brominating reagents and solvents following directions in standard organic chemistry manuals. We were particularly interested in learning which combination of brominating reagent and solvent gave the best yield of (d,l)-1,2-dibromo-1,2-diphenylethane without the formation of significant amounts of meso-1,2-dibromo-1,2-diphenylethane, which is essentially the sole product from the reaction of bromine with (E)-1,2-diphenylethene (trans-stilbene). Based on the results from the standard preparatory methods, some permutations of solvent and brominating reagent were tried. Amburgey-Peters, Judith C.; Haynes, LeRoy W. J. Chem.

A Substitute for “Bromine in Carbon Tetrachloride” Joshua M. Daley and Robert G. Landolt Benzotrifluoride (BTF) is a suitable solvent substitute for carbon tetrachloride in experiments requiring application of bromine (Br2) in free radical or addition reactions with organic substrates. A 1 M solution of Br2 in BTF may be used to distinguish hydrocarbons based on the ease of abstraction of hydrogen atoms in thermally or light-induced free radical substitutions. Efficacy of minimization of solvent use, by aliquot addition to neat samples, has been established. Daley, Joshua M.; Landolt, Robert G. J. Chem. Educ. 2005, 82, 120.

A Simple Method for Demonstrating Enzyme Kinetics Using Catalase from Beef Liver Extract Kristin A. Johnson A simple visual method of demonstrating enzyme kinetics using beef liver catalase. Filter paper is saturated with beef liver extract and placed into a solution of hydrogen peroxide. The catalase in the extract decomposes the hydrogen peroxide to water and oxygen. Oxygen forms on the filter paper, and the filter paper rises to the top of the beaker. Catalase activity is measured by timing the rise of the enzyme-soaked filter paper to the top of beakers containing different concentrations of hydrogen peroxide. Johnson, A. Kristin. J. Chem.

Periplanar or Coplanar? Saul Kane and William H. Hersh The prefix peri, derived from the Greek for "near", was chosen to make the meaning "approximately planar". However, the current common usage of syn and antiperiplanar is planar, which is incorrect. In the interests of proper language, we suggest that future authors instead use "syn-coplanar" and "anti-coplanar". Kane, Saul; Hersh, William H. J. Chem. Educ. 2000, 77, 1366.

General Potential Energy Surfaces for Catalytic Processes S. H. Bauer Here we argue that one may describe, in general terms, how catalysts modify reaction mechanisms by entering and leaving a conversion sequence, using potential energy surfaces that are conceptually correct. Thermochemical and kinetic constraints providing bounds that limit catalytic processes are formulated. 3-D diagrams are proposed. These clearly illustrate the basic principle that catalysts initially associate with the substrates and thus directly participate in modified conversion pathways, but are regenerated in the final step, thereby providing for a turnover number greater than unity.

The flow rate of hydrogen chloride gas into the flask in the smoke fountain is not constant, but periodic; that is, the smoke puffs from the end of the tube. This unexpected behavior elicits an interesting thermodynamic explanation. Alexander, M. Dale. J. Chem. Educ. 1999, 76, 210.

What are Isodesmic Reactions? D. A. Ponomarev and V. V. Takhistov The heat of isodesmic (formal) reaction Q is systematically used as a measure of deviations from the additivity of bond energies. For molecules these Q values are applied to quantification of strain energies in cyclic compounds, to evaluation of aromaticity of benzene, to explanation of the reasons for deviation from additivity in the heats of formation for disubstituted benzenes and some alkenes.
