When α-acetylenic alcohols are reacted with acid chlorides of trivalent phosphorus in the presence of a tertiary base, the intermediate trivalent esters rearrange to pentavalent phosphorus derivatives, with formation of a new PC bond. Generally, the C3 group fixed on the phosphors has an allenic structure: ; in some cases this group tautomerizes to the corresponding acetylenic derivative: .
当α-炔醇在叔碱的存在下与三价磷的酰氯反应时,中间体三价酯会重排为五价磷衍生物,并形成新的PC键。通常,固定在磷光体上的C 3基团具有烯丙基结构:在某些情况下,该基团互变异构为相应的炔属衍生物:。
