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

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.

Key Words:

• Boron-sulphur compounds
• 2(dialkyl and alkylene dithiophosphato)-1,3,2-dioxaborinanes.
