Monothiophosphorylation of Diorganotin Dichlorides. Synthesis and Characterization

Abstract

Reactions of diorganotin dichlorides with ammonium dialkyl monothiophosphates in refluxing benzene in 1:2 molar ratio yield diorganotin bis(dialkyl monothiophosphate). These compounds are soluble in common organic solvents. Molecular weight determinations show that these compounds are associated in solution and the degree of association is concentration dependent. The new compounds have been characterized by elemental analyses as well as spectroscopic (IR, ¹H, ¹³C, ³¹P and ¹¹⁹Sn) studies. On the basis of these data, chelate structures have been proposed.
