ABSTRACT:
Benzopinacol compounds can be prepared by an improved process comprising irradiating a diarylketone with UV radiation in a non-polar hydrocarbon solvent mixed with an alcohol. The volume ratio of the non-polar hydrocarbon solvent to alcohol is between 3:1 and 8:1. The benzopinacols are useful, for example, in imaging materials, such as with certain dyes that are reactive with the ketyl radicals that can be released from the benzopinacols upon heating.
