ORGANIC DERIVATIVES OF ALKYLENE DITHIOPHOSPHATE: PART I. SYNTHESIS AND PROPERTIES OF 2-ACYL(BENZOYL) ALKYLENE DITHIOPHOSPHATES

Abstract

Organic derivatives of the type (where G = [sbnd]CMe₂CMe₂[sbnd], [sbnd]CH₂CMe₂CH₂[sbnd], [sbnd]CMe₂CH₂CHMe[sbnd], [sbnd]CH₂CH₂CHMe[sbnd]; R = [sbnd]Me, [sbnd]Ph) have been synthesized by the reactions of acetyl chloride/benzoyl chloride with O.O′-alkylene dithiophosphoric acids (or ammonium salts), which yields the red colored viscous liquids or sticky solids, soluble in common organic solvents. The newly synthesized derivatives have been characterized by elemental analysis, IR and NMR (¹H and ³¹P) spectral studies. In contrast to the bidentate chelating behaviour of the ligand in metal and organometal derivatives of alkylene dithiophosphates, the behaviour of dithiophosphate moiety in these derivatives is found to be monodentate.

Key Words:
