Irradiation of (arene)M(CO)3 complexes (M = Cr, Mo, W; arene = various benzene derivatives) in the presence of H2 results in CO extrusion and subsequent reaction with H2. For chromium and molybdenum, the resulting complexes have moderate thermal stability and are identified as sigma complexes of H2 by NMR spectroscopy. Analogous tungsten reactions require prolonged irradiation in the presence of H2
