## Abstract The only stable organometallic carbene complexes of silver and copper are those of N‐heterocyclic carbenes, since formally these robust divalent carbon ligands bind only by a σ donor interaction to the metal. A survey of the range of complexes that have now been reported is presented. ©
## Abstract **Undue influence**: N‐heterocyclic carbenes (NHCs) were found to reduce the strength of the BH bonds of borane by a surprisingly large amount upon the formation of NHC–BH~3~ complexes. This property was exploited in the development of a suite of NHC–borane complexes for the reduction
## Abstract N‐Heterocyclic carbenes (NHCs) possessing one or two 3,4‐dimethylphosphaferrocenyl substituents and either methylene or ethylene alkyl bridges have been prepared. These carbenes turned out to be remarkably stable and were characterized by NMR methods and partly by mass spectrometry. The
