Abstract

Summary The free-radical decomposition of 0.0-t-butyl and 0-isopropenyl peroxycarbonate in substrates possessing mobile H-atoms (SH) consists mainly in an induced chain process leading to acetonylated derivatives of the solvent. Fairly good yields are obtained but the acetonylation of functional substrates often gives mixtures of isomers. In the case of methyl acetate, the acetonylation occurs on the C-atoms adjacent to the carboayl (acyloxy moiety) ...
