The reaction of tri-Et phosphite with di-Et trichloromethylphosphonate 2b in the absence of solvents and catalysts yields mainly di-Et (1,1-dichloropropyl)phosphonate and di-Et dichloromethylphosphonate. These main products are accompanied by a variety of byproducts which differ considerably from those obtained in the reaction between tri-Et phosphite and CCl4. Both reactions would begin by a halophilic substitution of tri-Et phosphite on the pos. halogen. For di-Et trichloromethylphosphonate the formed carbanion would then attack preferentially the C β to P+ and the H γ to P+ on heterophosphonium cation. In contrast, the less sterically hindered trichloromethyl carbanion formed by the halophilic attack of tri-Et phosphite on CCl4 would rather attack mainly the pos. P+ of this cation. The tetra-Et (dichloromethylene)bisphosphonate previously reported by V. P. Kukhar and E. I. Sagina (1979) to be the main product formed in the thermal reaction between tri-Et phosphite and di-Et trichloromethylphosphonate was not found under the authors’ conditions. Its formation only under photochem. irradiation were observed
