Synthesis and isolation of a stable, axially-chiral seven-membered N-heterocyclic carbene.

ABSTRACT: A chiral seven-membered N-heterocyclic carbene (NHC) has been synthesized from its phenol adduct (NHC-HOPh) by a novel base-induced alpha-elimination method, and its donor strength has been determined from the IR stretching frequencies of the NHC-Rh(CO)(2)Cl complex.
