  Photochemical and thermal disproportionation of [(CO)4CoM(CO)3(LL)] (M  Mn, Re; LL = 2,2′-bipyridine, 2-pyridinecarbaldehyde N-isopropylimine) complexes

  摘要：

  A study has been made of the secondary thermal reactions occurring after MLCT photolysis of [(CO)4CoRe(CO)3(LL)] (LL = 2,2'-bipyridine, 2-pyridinecarbaldehyde N-isopropylimine). Contact ion pairs {[Re(CO)3(LL)]+[Co(CO)4-]} have been detected as final products upon irradiation into the MLCT band of the Re complexes in toluene. The initial quantum yield of the 476.5 nm photolysis of the 2,2'-bipyridine complex in toluene at 223 K is independent of the concentration and light intensity, implying that the contact ion pairs are formed by radical-radical interaction without involvement of any other donor molecule. The quantum yields increase with temperature. At initial concentrations of 10(-2) mol 1(-1) with toluene as the solvent the photodisproportionation into contact ion pairs is strongly retarded at about 50% conversion; this effect seems to depend on the concentration of the contact ion pair. The complexes under study disproportionate thermally into ion pairs when their solutions in CH3CN or THF are left in the dark. In 2-MeTHF at T less-than-or-equal-to 243 K only [(CO)4CoMn(CO)3(2,2'-bipyridine)] undergoes disproportionation.

  摘要本文报道了两种金属-金属键合的配合物CpFe（CO）2Re（CO）3（α-diimine）（α-diimine= 4,4'-dimethyl-2,2'-bipyridine（ bpy'），吡啶-2-甲醛N-异丙基亚胺（iPr-PyCa），其特征在于在可见光区域内强烈允许金属到配体的电荷转移（MLCT）跃迁。在218 K，bpy'配合物（1）显示出与波长有关的光化学。低能激发进入MLCT谱带产生均质产物，用紫外线照射会释放出CO并形成CO桥连的光产物。iPr-PyCa配合物（2）在rt处已经显示出与波长有关的光化学反应。同样，在低能激发下金属-金属键发生均质。2的紫外线照射也导致CO的释放，但在这种情况下，形成了iPr-PyCa桥接的复合物。在该光产物中，也可以通过长时间照射2时通过自由基偶联机理形成，该iPr-PyCa配体很可能是σ-N，σ-N'与Re配位，η2-CN与Fe配位。从实验
