Abstract

International audience; Electronic and steric properties of NHC ligands functionalized with porphyrins were investigated. When porphyrins are used as NHCwingtips, nickel(II) in the macrocyle significantly improves the catalytic activity of the neighbouring NHC-Rh(I) complex in the conjugate addition of phenylboronic acid to cyclohexen-2-one.

Abstract

A porphyrin bearing four imidazolium rings on the meso positions was used as an N-heterocyclic carbene (NHC) precursor for the synthesis of porphyrin dimers with face-to-face orientations. The porphyrins are connected through the formation of eight M-CNHC bonds, with M = AgI or AuI.
