摘要

A series of new N-alkyl functionalised 6-and 7-membered expanded ring N-heterocyclic carbene (NHC) pro-ligands 3–6 and their corresponding complexes of rhodium (I) and iridium (I),[M (NHC)(COD) Cl] 7–14 and [M (NHC)(CO) 2Cl] 15–22 are described. The complexes have been characterised by 1H and 13C {1H} NMR, mass spectrometry, IR and X-ray diffraction. It is noted from X-ray diffraction studies that the N-alkyl substituents are ...
