Treatment of β-propiolactone with dialkylamino(dimethyl)arsines at 80° in benzene gave dimethylarsenic 3-dialkylaminopropionates, formed by alkyl–oxygen bond fission. The addition reactions of dialkylamino(dimethyl)arsines with 1,1,1-trichloro-2,3-epoxypropane took place with normal fission of the epoxide ring to give 2-dialkylamino-1-trichloromethylethoxy(dimethyl)arsines. Although 1-chloro-2,3-epoxypropane
用二烷基氨基(二甲基)dimethyl在苯中80°处理β-丙内酯,得到由烷基-氧键裂变形成的二甲基砷3-二烷基氨基丙酸酯。二烷基氨基(二甲基)ar与1,1,1-三氯-2,3-环氧丙烷的加成反应是在环通常裂变的情况下进行的,得到2-二烷基氨基-1-三氯甲基乙氧基(二甲基)ar。尽管1-氯-2,3-环氧丙烷的反应性不如三氯化合物,但其开环方式相同。这些反应产物的降解表明氨基ar中的亲核位点是氮而不是砷原子。
