Abstract

Abstract: Near-UV irradiation of (q5-CSR5) Fe (C0) 2 (q'-cH2C6H5)(R= H, Me) yields both loss of CO and CH2C6H5 radicals as primary photoprocesses, though the loss of CO dominates the excited-state chemistry. At 77 K in a rigid alkane matrix the only detectable photoreaction is loss of CO to form (? 5-C5RS) Fe (CO)(q3-CH2C6H5). In fluid alkane solution at 298 K the dominant metal-containing photoproduct is (qS-C5R5) 2Fe2 (C0) 4, ...
