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

摘要

The O,O-alkylene dithiophosphates of chlorodiorganotin(IV), ClR_2SnS_2POGO (where R = Me, G=-CMe_2CMe_(2~-); R = Me, Bu; G =-CH_2CMe_2CH_(2~-), and R = Me, Bu, Ph; G = -CHMeCH_2CMe_(2~-)) 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, ~(13)C, ~(31)P, and ~(119)Sn NMR spectroscopy. Unlike triorganotin derivatives, the ligand is bidentate in these derivatives.
