Refluxing a slightly acidic n-BuOH solution of RhCl(PPh3)3 and 2-chloro-, 2,4-dichloro-, or 2,4,6-trichloroazobenzene affords cyclometalated complexes (1) via loss of one phosphine ligand and oxidative addition 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.
