Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be
