Deprotonation of chiral triazolium salts 1 and reaction of the resulting nucleophilic carbenes with [(COD)RhCl]2 or [(NBD)RhCl]2 afforded square-planar complexes 2–6 in yields of 65–95%. The complexes contain an axis of chirality and a diastereomeric excess of up to 97% was achieved. The relative and absoluteconfigurations of these complexes were determined by NMR spectroscopic investigations and
