摘要
2-和 3 -二茂铁甲酰基 -1 ,1′-二丙基二茂铁经 Li ALH4 还原为 2种相应的二丙基双二茂铁甲醇。这 2种羟基化合物与 BF3在二氯甲烷中作用得到二丙基双二茂铁甲基碳正离子。该离子可直接与胺作用 ,形成产率较高的 N-取代产物。由元素分析 ,IR和 1
The reduction of 2 and 3 ferrocenylformyl 1,1 dipropylferrocenes by LiAlH 4 gave the relevant dipropylferrocenylmethanols.The two hydroxyl compounds reacted with BF 3 in CH 2Cl 2 to give the relevant dipropyldiferroceylmethyl carbocations.The ions reacted with amine RNH 2 directly without separation from the solution and gave N substituted compounds in high yields.The structures of these new compounds were characterized by elementary analysis,IR and 1HNMR.
