Abstract
The O, O-alkylene dithisphosphates of triorganotin(IV) of the general formula R 3SnS 2PO 2G (where R = C 6H 5, n-C 4H 9, n-C 3H 7, n-C 2H 5 and CH 3; G = CH 2C(CH 3) 2CH 2, C(CH 3) 2C(CH 3) 2 and C(CH 3) 2CHCH 3 have been synthesized by treatment of triorganotin(IV) chlorides with ammonium O, O-alklene dithiophosphates in 1/1 molar ratio in benzene. These novel complexes are either white crystalline solids or distillable liquids; all are soluble in common organic solvents are are monomeric in refluxing benzene. Like dialkyldithiophosphate derivatives of triorganotin(IV), these cyclic chain derivatives appear to be tetrahedral, the ligands behaving as unidentates.
