Mixed Chloro Derivatives of Vanadium Dialkyl and Alkylene Dithiophosphates

Abstract

Mixed chloro vanadium derivatives of dialkyl and alkylene
dithiophosphates of general formula CIV[S₂P(OR)₂]₂ where R = Prⁿ and
Ph and cyclic  where G = — CH₂— CMe₂— CH₂—,
CMe₂CMe₂— and —CH₂CEt₂CH₂— have been synthesized by the reaction
of vanadium trichloride with dithiophosphoric acids in 1 : 1 and 1 : 2
molar ratio in suitable organic solvents. These new derivatives have been
characterized by elemental analysis. molecular weight determinations as
well as spectroscopic (IR, ¹H,  ¹³C and ³¹P NMR) studies. On the basis of
these data chelated structures with bidentate dialkyl and alkylene
dithiophosphate groups have been proposed for these monomeric derivatives.
