The treatment of 4-benzoyltetrahydrofuran-2,3-dione (2a) with 2 equiv. of phenyllead triacetate (3a) in chloroform gives 1,2-diphenylpropenone (4a) in excellent yield.This reaction has been investigated with a number of similar derivatives of tetrahydrofuran-2,3-dione and a number of aryllead triacetates.It has been found to be very sensitive to the nature of the substituent at C4, and it would appear to be limited to the synthesis of α-methylene carbonyl compounds since a 5-methyl substituent inhibits the reaction.
