Synthesis and characterization of chlorodiorganotin(IV) derivatives of O,O-alkylene dithiophosphates

The O,O-alkylene dithiophosphates of chlorodiorganotin(IV), (where R = Me, G =–CMe2CMe2–; R = Me, Bu; G =–CH2CMe2CH2–, and R = Me, Bu, Ph; G =–CHMeCH2CMe2–) have been synthesized by reactions of diorganotindichloride with the ammonium salts of O,O-alkylene dithiophosphates in 1 : 1 molar ratio in benzene. These compounds have been characterized by IR, 1H, 13C, 31P, and 119Sn NMR spectroscopy. Unlike triorganotin derivatives, the ligand is bidentate in these derivatives.
