Pyrolysis of Aryl Sulfonate Esters in the Absence of Solvent: E1 or E2? A Puzzle for the Organic LaboratoryJohn J. Nash, Marnie A. Leininger, and Kurt Keyes An aryl sulfonate ester is synthesized and then pyrolyzed at reduced pressure. The volatile products are analyzed using gas chromatography to determine whether the thermal decomposition occurs via an E1 or E2 mechanism. Nash, John J.; Leininger, Marnie A.; Keyes, Kurt. J. Chem. Educ.2008, 85, 552.

Rapid and Stereoselective Conversion of a trans-Cinnamic Acid to a β-BromostyreneThomas 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. Evans, Thomas A. J. Chem. Educ.2006, 83, 1062.
Kinetica; An Excel program to Stimulate or Analyze Kinetic DataLeonel Vera, Pedro Ortega, Miguel Guzmán The Excel spreadsheet Kinetica both simulates and analyzes kinetic data for simple rate equations of the form: - d[A]/dt = k [A]^n Instructors or students can generate simulated kinetic data using parameters they specify, or using parameters randomized by Kinetica. The data set that is generated may then be exported for use in exercises, homework, and exams, or may be analyzed directly within Kinetica. A kinetics data set may also be imported from an external source into Kinetica for analysis.
Kinetics
An Excel Program to Study First-Order KineticsKen Muranaka User data can be analyzed to determine what parameter values of the first order rate expression give the closest fit, or data can be generated using user-input values of the rate parameters and random noise levels. Statistical characterizations such as confidence limits and variance are calculated.
