condensation of carbanions of α-chloro-α-lithiated phosphonates with carbonyl precursors gives direct access to α-chlorine-β-carbonyl phosphonates. The reactions with ethylformate, dimethylformamide, carboxylic esters, diethyl carbonates, diethyl oxalates etc. are discussed. In each case the intermediates have been identified.

Reactions of phosphorylated α-haloacetaldehydes with difunctional nitrogen-, oxygen-, and sulfur-containing nucleophiles were performed with a view to synthesize C-phosphorylated heterocyclic compounds.
