phoiphoranes , , , , , to by addition of a trivalent phosphorus compound (phosphites and amino-phosphines ) to with dimethyl acetylencedicartboxylate in presence of a protic trapping reagent are described. The results are consistent with trapping of carbanionic species. In relation with the. cyclic of acyclic structure of the triivalent phosphorus compound and the protic trapping reagent ie : methanol, phenol
的新的无盐内鎓盐的合成,对,,,,和和phoiphoranes ,,,,,以通过添加三价磷化合物(亚磷酸酯和氨基膦)到描述了在质子俘获试剂的存在下用乙炔基乙二酸二甲酯二甲酸酯与乙炔基二羧酸二甲酯联用。结果与碳负离子物质的捕集是一致的。与之有关。三价磷化合物和质子捕获剂(如甲醇,苯酚,羧酸等)的无环结构的环状,涉及多个途径。显然)显示出三种现象:一种可以通过膦烷获得一个碘,或者相反地通过一个膦或平衡的磷杂环戊烷获得一个磷烷。结果涉及热力学或动力学控制的反应。
