摘要：

Tungsten complex [W(NHC)(CO)(5)] (1) (NHC=NH,N-ethyl-substituted benzimidazolin-2-ylidene ligand) was prepared by transmetallation of lithiated 1-ethylbenzimidazole with the pentacarbonyltungsten complex fragment. The hydrogen-bonding ability of the carbene-NH group to substrates with carbonyl groups was investigated by NMR titration. Structural analogues to 1 with a catalytically active rhodium center show a distinct substrate-s elective hydrogenation behaviour. (c) Wiley-VCH Verlag GmbH & Co.
