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.
二乙基1,1-二氯甲基膦酸酯(2)通过使用i-C3H7MgCl还原1,1,1-三氯甲基膦酸酯(1)后进行水解合成,并获得了良好的产率。研究了化合物2对α-烷基化的反应性以及其在合成氯乙炔和末端乙炔中的应用。
