Description

The aprotic polar solvents, such as DMF (N,N-dimethylformamide) and DMSO (dimethyl sulfoxide), accelerated very effectively the methylenation of 1,2-dihydroxy-4- (I), 1,2-dihydroxy-3,4-dimethoxy-5- (II), and 1,2-dihydroxy-3-methoxy-5-allylbenzene (III) in the presence of bronze and cupric oxide as catalysts.
