A NEW ROUTE TO 1,2-DITHIOLE-3-THIONES (TRITHIONES) BY THE REACTION OF ENAMINONES WITH CARBON DISULFIDE

Enaminones reacted with carbon disulfide in the presence of sodium hydroxide to give the corresponding 1,2-dithiole-3-thiones (trithiones) in 30-82percent yields.

Thionation Reactions of Diacylketene Thioacetals with the Lawesson Reagent and Analogues

Attempted thionation of diacylketene thioacetals derived from dimedone with dithiadiphosphetane disulphides (the Lawesson reagent and analogues) led to the expected monothioacylketene thioacetals only when the thioacetal sulphur atoms formed part of a dithiolane or dithiane ring.Acyclic analogues readily underwent dealkylation and further reactions, giving a 1,2-dithiole-3-thione derivative as the main isolated product.Reaction of an acyclic ketene thioacetal with P4S10-Et3N in acetonitrile at -30 deg C permitted the isolation of the primary dealkylation product, a dimedonedithiocarboxylate, in 44percent yield.A phenoxaphosphorine derivative was isolated as a by-product in the synthesis of bis(phenoxyphenyl)dithiaphosphetane disulphide.
