Abstract The mechanism of sulfurization of substituted triphenylphosphines with 4-(3-and 4- substituted)-1, 2, 4-dithiazolidine-3, 5-diones in acetonitrile, dichloromethane, tetrahydrofuran and toluene at 25 C was studied. The reaction pathway involves rate-limiting initial nucleophilic attack of the phosphorus at sulfur followed by fast decomposition of the phosphonium intermediate to the corresponding phosphine sulfide, phenylisocyanate and ...
