, p. 431 - 437 (2007/10/02)
A convenient general method for the synthesis of compounds containing a thiophosphoryl group was elaborated on the basis of the Michaelis-Becker reaction with the use of the method of phase-transfer catalysis. The influence of the nature of the hydrothiophosphoryl compounds, of the alkylating agents, and of the reaction conditions on the yields of alkylated products was investigated in detail.

1. The equilibrium CH-acidity (pK) of phosphine oxides and phosphine sulfides of analogous structure was determined in diglyme (DG) and in DMSO by the method of transmetallation. The acidity of the phosphine sulfides is almost unchanged from one solvent to another. The acidity of phosphine oxides in relatively nonpolar DG is three to five orders of magnitude higher than in DMSO, on account of the coordination of the phosphoryl group of the carbanions with the alkali metal cation in DG. The ionic dissociation constants of Li-substituted phosphine oxides in DG are two to three orders of magnitude lower than for phosphine sulfides. The distance between ions in ion pairs in Li-substituted phosphine oxides is reduced. 2. For an estimation of the acidifying effect of phosphinyl and thiophosphinyl groups, we used the pK in DMSO. Thiophosphinyl substituents negligibly exceed phosphinyl groups in their summary acidifying effect. 3. The introduction of (C6H5)2PO and (C6H5)2PS groups as substituants into diphenylmethane and fluorene increases the acidity of the latter by ～8 units of pK.
