(matrix presented) Treatment of aromatic α/β-unsaturated carbonyl compounds with Mg turnings in the presence of acid anhydrides/TMSCI or acyl chlorides in DMF brought about a facile and efficient cross-coupling to give C-acylation products, which are usef

(Chemical Equation Presented) The cis and trans diastereoisomers of 5-(diethoxyphosphoryl)-5-methyl-4-phenylpyrroline N-oxide (4-PhDEPMPOt 8 and 4-PhDEPMPOc 9) were prepared stereoselectively and used as spin traps for hydroxyl and superoxide radicals. Th
Electrochemical Acylation and Carboxylation of Some Activated Olefins

The electrochemical acylation and carboxylation of some activated olefins have been investigated.Acenaphthylene yields thus on reductive electrochemical acetylation mainly the Z and E enol acetates of 1-(1,2-dihydro-1-acenaphthylidene)ethanone, whereas carboxylation followed by methylation gives trans-1,2-dimethoxycarbonyl-1,2-dihydroacenaphthene.Ethyl cinnamate can be acylated and carboxylated in the 3-position, whereas benzoylacetone could be carboxylated but not acetylated.Neither carboxylation nor acylation were able to compete with the dimerization of benzylidenemalonitrile.Cyclic voltammetry showed that carboxylation generally was faster than acetylation.
