摘要

Abstract 1, 3-Dithianes 2 can effectively be converted in to the parent carbonyl compounds 7 by a very mild oxidative procedure using tri-p-tolylammoniumyl (1a+.) or tris (4- bromophenyl) ammoniumyl (1b+.) as homogeneous electron transfer agents. The yields are equally good for the cleavage by stoichiometric amounts of the triarylammoniumyl hexachloroantimonates as well as for the indirect electrochemical procedure using ...
