Facile methods of the synthesis of S‐trialkylstannyl esters of dithio‐ and tetrathiophosphoric acids

S-Trialkylstannyl dialkyldithiophosphates 3 and tetrathiophosphates 6 were easily obtained in the reaction of tetraphosphorus decasulfide 1 with trialkylalkoxystannanes 2 or alkylthiostannanes 5 under mild conditions. Tetraphosphorus decasulfide 1 and hexaalkyl distannylsulfides 4 produce tris(trialkylstannyl) tetrathiophosphates 9.
