摘要：

Rhodium and iridium complexes of N-heterocyclic carbenes (3a-c and 4a-c) were obtained by transmetalation from the corresponding Ag(I) complexes. The structure of 3b was verified by X-ray diffraction. The compounds display restricted rotation about the metal-carbene bond, the rate of which can be controlled by altering the steric bulk of the auxiliary ligands. Infrared spectroscopy provides an estimate of the electron-donor power of the carbene ligands from v(CO) of the carbonyl derivatives.
