Abstract:

The imidazol-2-ylidene complexes I [M = Cr, Mo, W, R = Me; M = W, R = Et (II), CHMe2] are obtained from M(CO)6 and the corresponding imidazol-2-ylidenes in 87-96% yields. 13C-NMR data and the x-ray structure of II confirm the carbenes to be strong donor ligands, no evidence for significant p-interaction between the carbene C atom and the metal center being detected.
