6-trichloroazobenzene affords cyclometalated complexes (1) via loss of one phosphine ligand and oxidativeaddition of the ortho -C-Cl bond. X-ray structural analysis indicates a trans-position of the two triphenylphosphine ligands. The reaction proceeds only in polar solvents like alcohols or dimethyl sulfoxide but not in toluene. In the presence of air or oxygen a hydrido complex was formed as a by-product.
