product studies of the solvolyses of acyclic phosphorochloridates are extended to two cyclic diesters, 2-chloro-1,3,2-dioxaphospholane-2-oxide (1) and 2-chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane-2-oxide (2). Slightly faster solvolyses are observed for 1 than for the acyclic dimethyl phosphorochloridate (3), and 2 solvolyzes somewhat slower than 3. An extendedGrunwald–Winsteinequation treatment

The extendedGrunwald-Winsteinequation is applied to solvolytic displacement at phosphorus. Previous studies of the solvolyses of phosphorochloridates (RO)2POCl, Ph2POCl and [(CH3)2N]2POCl are extended to cyclic phosphorochloridates, with five and six membered rings. Both kinetic and product ratio measurements are made. The equation is also applied to kinetic studies of the solvolyses of Ph2PCl. The
扩展的 Grunwald-Winstein 方程适用于磷的溶剂分解位移。先前对氯化磷 (RO)2POCl、Ph2POCl 和 [(CH3)2N]2POCl 的溶剂分解的研究扩展到具有五元环和六元环的环状磷氯化物。进行动力学和产物比率测量。该方程也适用于 Ph2PCl 溶剂分解的动力学研究。将 l 和 m 灵敏度值与之前的值和硫侵蚀值进行比较,以提供有用的机械信息。
