This experiment was designed to provide experience in preparing compounds using a two-step synthetic scheme. The first step is a light-catalyzed radical reaction and the second-step is an elimination/rearrangement reactions. The first step is the conversion of benzophenone to bezopinacol using a photochemical reaction. Photochemical reactions often involve free radical species which are compounds with an unpaired electron. Free radical compounds are very reactive and are involved in reactions such as hydrogen abstraction, radical coupling, and polymerizations. The second step of this reaction series is the acid catalyzed dehydration of benzopinacol followed by rearrangement to benzopinacolone. This reaction illustrates the concept of carbocation rearrangement to a more stable carbocation. In this reaction, a tertiary carbocation rearranges to a more stable carbocation.
