摘要: Irradiation of the complexes (CO)5MnMn(CO)3(α-diimine) into their visible absorption band gives rise to homolysis metal-metal bond and release CO from Mn(CO)3(α-diimine) moiety. Only reaction leads product formation at room temperature, loss is only observed low temperatures. The radicals formed by undergo very interesting radical coupling electron transfer (chain) reactions. mechanisms these reactions are discussed attention paid character excited state which take place. corresponding halide Mn(CO)3(bpy)X show a similar Mn(CO)3(bpy) radicals. Preliminary m.o. data (X=C1,I) resonance Raman spectra obtained for Re(CO)3(PTol-DAB)Br confirm presence lowest LLCT complexes.
