5-dimethyl-1,3,2-dioxaphosphorinan, diethyl phosphorochloridate and O,O-diethyl phosphorochloridothionate respectively. It has been found that alkaline hydrolysis of these anhydrides occurs with full inversion of configuration at the thiophosphoryl centre. The reaction is discussed from the point of view of stereochemistry and the reaction mechanism.
在旋光的O-乙基乙基膦酸硫代酸(I)与2-氯-2-氧代-5,5-二甲基-1,3,2-二氧杂磷酰氨基己酸酯之间的反应中获得了旋光的焦膦酸酯(II,III和IV),氯代磷酸二乙酯和硫代磷酸氯代O,O-二乙基酯。已经发现这些酸酐的碱水解发生在硫代磷酰基中心的构型完全反转的情况下。从立体化学和反应机理的角度讨论了该反应。
