Diethyl 1,1-dichloromethylphosphonate (2) was synthesised in good yield from the reduction of 1,1,1-trichloromethylphosphonate (1) with i-C3H7MgCl and subsequent hydrolysis. The reactivity of 2 towards α-alkylation and its utility in the synthesis of chloroalkynes and terminal alkynes was investigated.
