reacts with triphenylphosphine or triethyl phosphite to form phosphonium salts 3 and 7 which fragment to an iodide 4 upon heating. The mechanism of C–C bond formation induced by phosphine and phosphite is discussed. A 1,3,2-dioxaphospholane 8 was synthesized from diketone 1 in two steps through an intermediate diol 10, although an attempt for a direct condensation of 1 and triphenylphosphine was unsuccessful
碘酮2与三苯基膦或亚磷酸三乙酯反应形成phospho盐3和7,它们在加热时片段化成碘化物4。讨论了由膦和亚磷酸酯诱导的CC键形成机理。从二酮1分两步通过中间体二醇10合成了1,3,2-二氧杂磷杂环戊烷8,尽管尝试将1与三苯基膦直接缩合没有成功。通过半经验计算可以使反应合理化。报告了3和8的晶体衍射分析,并将其中一些键合参数与计算值进行了比较。
