Regioselectivity in Organic Synthesis: Preparation of the Bromohydrin of α-Methylstyrene Brad Andersh, Kathryn N. Kilby, Meghan E. Turnis, and Drew L. Murphy
In the described experiment, the regiochemical outcome of the addition of "HOBr" to a-methylstyrene is investigated. Although both "classic" qualitative analysis and instrumental techniques are described, the emphasis of this experiment is on the utilization 13C and DEPT-135 NMR spectroscopy to determine the regiochemical outcome of the addition.

Microwave-Assisted Organic Synthesis in the Organic Teaching Lab: A Simple, Greener Wittig Reaction Eric Martin and Cynthia Kellen-Yuen
A microwave-assisted Wittig reaction has been developed for the organic teaching laboratory. Utilizing this technique, a variety of styrene derivatives have been synthesized from aromatic aldehydes in good yields. The mixture of cis and trans alkenes produced also provides instructors with opportunities to emphasize the spectroscopic analysis of product mixtures.

Computational Analysis of Stereospecificity in the Cope Rearrangement Laura Glish and Timothy W. Hanks
Experimental product distributions from the Cope rearrangement of disubstituted 1,5-hexadienes can be readily understood by computer modeling of the various possible transitions states. Visual analysis of these geometries allow students to interpret the computational results by analogy to the familiar chair and boat conformations of substituted cyclohexanes.

Polar Addition to C=C Group: Why Is Anti-Markovnikov Hydroboration–Oxidation of Alkenes Not "Anti-"? Predrag-Peter Ilich, Lucas S. Rickertsen, and Erienne Becker
The authors redefine Markovnikov or anti-Markovnikov regioselectivity and propose that the teaching of organic chemistry should be based on robust and portable concepts such as energy difference and atomic charge rather than historical labels.

Was Markovnikov's Rule an Inspired Guess? Peter Hughes
A study of 19th century literature shows that neither Markovnikov nor any of his contemporaries carried out the reactions often attributed to himthe addition of hydrogen bromide or hydrogen chloride to propene. Since there is little evidence for Markovnikov's rule in his 1870 article, it is likely that it was more of an inspired guess than a rational conclusion.

Rapid and Stereoselective Conversion of a trans-Cinnamic Acid to a β-Bromostyrene Thomas A. Evans
The stereoselective synthesis of an aryl vinyl bromide is accomplished in a rapid microscale reaction of trans-4-methoxycinnamic acid with N-bromosuccinimide in dichloromethane. This guided-inquiry experiment links reactivity, stereochemistry, and mechanism in electrophilic addition reactions of alkenes and in E1 and E2 elimination reactions that form alkenes.

Cis and Trans Isomers of Cycloalkenes Susan E. Barrows and Thomas H. Eberlein
The purpose of this article is to provide that analysis. In order for a cycloalkene to accommodate a trans double bond one or more of the following nonideal geometries must occur: a twisted p bond; pyramidal sp2-carbon atoms; nonideal sp3 bond angles; or longer than normal CC single and double bonds. This article provides a list of experimentally determined relative energies of the cis and trans isomers within the series cycloheptenecycloundecene, along with computationally derived energies at several levels of theory. It also examines the geometric distortions through which cycloalkenes relieve the strain introduced by a trans double bond.

Understanding Rotation about a C=C Double Bond Susan E. Barrows and Thomas H. Eberlein
We present a simple method of introducing the concept of a flexible C=C pi bond into beginning organic chemistry courses. We report the energetic demands of partial twisting about the C=C bond in 2-butene as calculated using DFT, LMP2, and MCSCF methods. Finally, using the results of these calculations, we assessed the degree of strain introduced by the twisted nature of the C=C bond in trans cycloalkenes.

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.

Cis and Trans Isomerization in Cyclic Alkenes: A Topic for Discovery Using the Results of Molecular Modeling Susan E. Barrows and Thomas H. Eberlein
This article describes an activity in which students are led to discover the fundamental reasons behind the unusual instability of the trans isomers in medium-sized cycloalkenes by using the results of molecular modeling. Notably, students will make the unexpected discovery that twisting about p bonds is perhaps more facile than they had been led to believe.

Solvent-Free Wittig Reaction: A Green Organic Chemistry Laboratory Experiment Sam H. Leung and Stephen A. Angel
In this experiment (E)- and (Z)-1-(4-bromophenyl)-2-phenylethene are synthesized by a solvent-free Wittig reaction. The reaction is effected by grinding the reactants in a mortar with a pestle. Both the E and Z isomers of the product are produced as evidenced by thin-layer chromatography and 1H NMR analysis. The E isomer is isolated by crystallization with ethanol in this experiment. In addition to learning about the Wittig reaction, students are also introduced to the ideas of mechanochemistry and green chemistry.

S. M. Tanatar and His Contribution to the Field of Thermal Rearrangements Ludmila Birladeanu
Thermal rearrangements constitute an important chapter in organic chemistry. Surprisingly, the name of its discoverer remains unknown. The present article is meant to remedy this situation by describing some of the work of the 19th century Russian chemist S. M. Tanatar (1849 - 1917) who, based on the thermochemical data provided by Berthelot, envisaged the possibility of transforming cyclopropane into propene under the influence of heat alone.
