Abstract

Thioalkoxyphosphonium salts, Ph 3 P+ SR ClO-4 (3) and Bu 3 P+ SR X-(X= ClO 4 and BF 4)(5), have been prepared from the corresponding tertiary phosphines and disulfides by simple procedures, which involve (i) constant current electrolysis in acetonitrile in the presence of either HClO 4 (for 3) or PhCOOH and LiX (for 5), and (ii) stirring an equimolar mixture of a phosphine, a disulfide, PhCOOH, and LiX in acetonitrile at ambient ...
