Syntheses and Spectroscopic Studies of O,O'-Dialkyl(Alkylene)Dithiophosphates of Trimethylaminoboranes

Abstract

O,O'-Dialkyl (or alkylene) dithiophosphates of trimethylaminoborane of the types B[S₂P(OR)₂]₃.NMe₃ and B[S₂POGO]₃.NMe₃ (where R = Me, Et, Prⁱ, Buⁱ, Ph; G = -CMe₂CMe₂- and -CH₂CMe₂CH₂-) have been synthesized as monomeric, white crystalline solids, soluble in common organic solvents and are characterized by elemental analyses, molecular weight measurements, IR and multinuclear (¹H, ¹¹B and ³¹P) NMR spectral studies which are consistent with four coordinated boron and the monodentate behaviour of the dithiophosphate moiety.

Key Words:

• Trimethylaminoborane
• O,O'-dialkyl- and alkylene dithiophosphates
