O-Alkyl Thioates and Dithioates, 33. - Reactions of Phosphorus Ylides with Thiooxalates - A New Synthesis of α,β-Unsaturated O-Alkyl Thioates

The reaction of dimethyl tetrathiooxalate (1) with alkylidenetriphenylphosphoranes 2 leads to the formation of triphenylphosphane sulfide (3) and a complex mixture of unstable products; with the disubstituted phosphoranes 4a, b the 1,3-dithioles 5 and triphenylphosphane (6) were isolated.O,O-Dimethyl dithiooxalate (8) is transformed into α,β-unsaturated O-alkyl thioates 9 by thiocarbonyl olefination with 2 and 4.
