α-官能化的膦酸酯和二硫化碳在碱存在下,反应生成连二硫酸盐中间体(1). 二价阴离子与烷基二卤化物的烷基化反应生成2-膦酰亚甲基-1,3-二硫代-环烷或与烷基卤化物反应生成烯酮缩硫醛, 再与脂族二胺反应生成2-膦酰亚甲基咪唑烷.

关键词: 二硫化碳, 膦酸酯类, 硫缩醛, 咪唑烷 P

The reactions of α-functional phosphonates with carbon disulfide in the presence of bases formed intermediates dithiolates (1). Alkylation of these dianions with alkyl dihalides gave 2-phosphonylmethylene-1,3-dithio-cycloalkanes or with alkyl halides gave ketene mercaptals which reacted with aliphatic diamines to afford the 2-phosphonylmethylene- imidazolidines (3).

Key words: PHOSPHONIC ACID ESTER, CARBON DISULFIDE, MERCAPTAL, IMIDAZOLIDINE P
