GRAPHICAL ABSTRACT ABSTRACT Reaction of P-chloroylides with carbonyl compounds leads to the formation of four-membered phosphorus heterocycles—2λ5-chloro-2,2-oxaphosphetanes. The 2-chloro-2,2-oxaphosphetanes depending on substituent R at α-atom carbon, rearrange with formation of 2-chloroalkylphosphonates (R = H, Alk, Ar) or with elimination of trimethylchlorosilane (R = Me3Si) convert into trans-phosphorylated
图形摘要摘要 P-氯酰化物与羰基化合物的反应导致形成四元磷杂环——2λ5-氯-2,2-氧杂膦烷。2-氯-2,2-氧杂膦烷取决于α-原子碳上的取代基R,重排形成2-氯烷基膦酸酯(R = H、Alk、Ar)或消除三甲基氯硅烷(R = Me3Si)转化为反式-磷酸化烯烃。
