Mono-N-heterocyclic carbene amido and alkyl complexes. Cobalt-mediated C–H activation and C–C coupling reactions involving benzylligands on a putative 3-coordinate intermediate

Abstract

Aminolysis of [Co(NHC){N(SiMe3)2}Cl] with N–H acidic compounds such as substituted amidines and anilines leads to novel Co(II) complexes with monodentate N-heterocyclic carbene ligation. Attempts to prepare Co(II) dibenzyl complexes with bulky IPr coligands led to metal reduction to Co(I) and aromatic C–H activation and C–C coupling between the benzyl groups.
