Ammonium acetate thiophosphates

Reactions of alkyl halides with diethyl phosphite in the presence of ammonium acetate/sulfur and acidic aluminia using microwave irradiation provide a simple and general route to thiophosphates. Two diastereoisomers of 1,3,2-dithiadiphosphetane 2-sulfide (19) have been isolated for the first time via the reaction of thioketones (20) with Lawesson s reagent (Figure 5). ...
