Saponification of trialkyl phosphorodithioates (R 1 O) 2 PSSR 2 can lead to the formation of sulfides in varying yields, together with the corresponding thiols. These reactions are not however widely applicable. Attack of cyclic phosphate esters by methanethiolate anion causes cleavage of a C O bond of the ester and gives a moderate yield of the sulfide (Equation (35)) < 93CC70 >.
