Three original approaches to the synthesis of N-alkyl-N′-phosphanylbenzimidazolium salts, which are precursors of the corresponding carbenes, were developed. New stable N-alkyl-N′-phosphanylbenzimidazol-2-ylidenes were prepared in good yields. X-ray analysis of a carbene was made and the chemical properties of the carbenes were studied. The reactions with O-, N-, and C-nucleophiles were found to proceed
开发了三种合成 N-烷基-N'-膦酰基苯并咪唑鎓盐的原始方法,它们是相应卡宾的前体。以良好的收率制备了新的稳定的 N-烷基-N'-膦酰基苯并咪唑-2-亚基。对卡宾进行了 X 射线分析并研究了卡宾的化学性质。发现与 O-、N- 和 C-亲核试剂的反应在 P-N 键断裂或不断裂的情况下进行。卡宾的热重排得到 2-磷酸化的苯并咪唑。
