Isomerisierungsreaktionen von cis- und trans-Dicarben-Komplexen des Typs M(CO)4L2 (M = Cr, Mo, W).

Isomerisation of cis- and trans-Dicarbene Complexes of the Type M(CO)4L2 (M = Cr, Mo, W)

  • Karl Öfele , Eva Roos and Max Herberhold

A series of bis-carbene complexes cis-M(CO)4L2 (M = Cr, Mo, W) containing cyclic carbene ligands (L= 1,2-dimethyl-4-pyrazoline-3-ylidene, 1,3-dimethyl-4-imidazoline-2-ylidene, 2,4-dimethyl-1,2,4-triazoline-3-ylidene and 1,3-dimethyl-benzimidazoline-2-ylidene) was prepared, and the photo-induced conversion to the corresponding trans-isomers was investigated. The trane-M(CO)4L2 complexes were characterized by their IR and 1H NMR spectra, and their irreversible thermal isomerisation to the thermodynamically more stable cis-isomers was studied both in solution and in the solid state.
