Abstract

The reaction of excited enones8 and quinones9J0 with alkenes and alkynes, which are the most extensively studied photoreactions, mostly led to the [2+ 21 photoadducts. We thus believe that the present reaction is not only of value in synthesis but is also of considerable mechanistic interest. We give here a full report of the results.
