METAL AND ORGANOMETAL COMPLEXES OF PHOSPHORUS OXY AND THIO ACIDS. PART VII. O,O′-DIALKYL(ALKYLENE) DITHIOPHOSPHATES OF BORON

Abstract

Abstract 2-(O,O′-Dialkyl and alkylene dithiophosphato)-1,3,2-dioxaborinanes, OGOBSP(S)(OR)2 and OGOBSP(S)OG′O, G = [sbnd](CH2)3[sbnd], [sbnd](CH2)2CHMe[sbnd], [sbnd]CH2CMe2CH2[sbnd]; R = Et, Prn, Pr2; G′ = [sbnd]CHWCHMe[sbnd], [sbnd]CMe2CMe2[sbnd], [sbnd]CMe2CH2CHMe[sbnd], [sbnd]CH2CMe2CH2[sbnd] have been prepared as monomeric, volatile and readily hydrolyzable liquids. These have been characterized by molecular weight, IR and multinuclear (1H, 11B, 13C and 31P) NMR spectral data which are consistent with three coordinate boron and monodentate dithiophosphate groups. These derivatives react with organotin oxides with ready transfer of dithiophosphato moieties from boron to tin.
