Aminocarbene complex anions [(CO)5MC(NH)R]− (M = Cr, Mo, W; R = Me, Ph) (1a–f), generated in situ by reaction of their conjugate acids with n-BuLi or MeLi, react with bis(diisopropylamino)chlorophosphane (2) to give lithium chloride and N-phosphanylsubstituted metal—carbene complexes [(CO)5M C(N(H)PR′2)R] (R′ = N′Pr2; R = Me, Ph) (3a–f), the first derivatives of this class of compounds. X-ray structure
氨基碳烯络合物阴离子[(CO)5 MC(NH)R] −(M = Cr,Mo,W; R = Me,Ph)(1a–f),是通过其共轭酸与n -BuLi或的MeLi,与双(二异丙基氨基)chlorophosphane(反应2),得到氯化锂和ñ -phosphanylsubstituted金属-卡宾配合物[(CO)5 M C(N(H)PR' 2)R](R' = N'Pr 2 ; R = Me,Ph)(3a–f),此类化合物的一阶导数。铬衍生物的X射线结构分析(3a:R = Me; 3d:R = Ph)和钼配合物(3b:R = Me)揭示了MC(R)N单元,具有氨基卡宾和亚胺基酰金属盐配合物的典型结构数据。
