Abstract

A short and flexible procedure for the preparation of 7 chiral azolinium and 5 functionalized chiral azolinium salts, precursors to N-heterocyclic carbenes, derived from L-proline has been developed. Moderate to good overall yields were obtained. Some NHC dimers and thiones were isolated. X-ray structure determinations of two [Rh-NHC] complexes were also reported.
