Abstract
Abstract 2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent) and its p-phenoxy derivatives react with 1,2-ethanediols and 1,4-butanediol at different reaction temperatures in acetonitrile as a solvent to give 1,3,2-dioxaphosphorinane-2-sulfide, thioacetamide and cyclic trithiopyrophosphonate. Compatible analytical and spectroscopic data were obtained for all the new compounds. A mechanism is proposed to explain the formation of compounds 5, 6, 7, 9 and 11. Reaction of 5a with LR gave 1,3,2-dithiaphosphorinane-2-sulfide.
