Synthesis and Characterization of O-Alkyl, O-Cycloalkyl and O-Aryl Trithiophosphato Derivatives of Trimethyl Tin(IV) Chloride and Tributyl Tin(IV) Chloride

Abstract Trimethyltin(IV)trithiophosphates [(RO)P(S)S2][Sn(Me)3]2 and tributyl tin(IV)trithiophosphates [(RO)P(S)S2][Sn(Bu)3]2 (R=CH3, –C2H5, –C3H7, –C3H7 iso –C4Hn 9, –C4H9 iso, –C4H5 scc, –C5H11 iso C6H11, –C6H5) were prepared in methanolic solution of R3SnCl and dipotassium salt of trithiophosphates in 2:1 molar ratio. These newly synthesised derivatives have been characterized by elemental analysis, molecular weight measurements, IR, 13C, 31P, and 119Sn,NMR spectral studies. Coordination number of four suggested for tin(IV) in these derivatives.
