Anionic derivatives of Fischer-type carbene complexes (A and B) are stable toward strong bases and nucleophiles, and their organic moieties R and R 2 can be elaborated under strongly basic conditions to provide access to heteroaromatic and aliphatic carbene complexes bearing organic functional groups. The concept of anionic protection has been illustrated by the reactions of dianions 9 and 14 and the
Fischer 型卡宾配合物(A 和 B)的阴离子衍生物对强碱和亲核试剂稳定,它们的有机部分 R 和 R 2 可以在强碱性条件下进行加工,以提供带有有机官能团的杂芳族和脂肪族卡宾配合物。阴离子保护的概念已通过二价阴离子 9 和 14 的反应以及具有多达四个手性中心的卡宾配合物的制备得到说明。还描述了一些实现芳族卡宾配合物邻位锂化的尝试
