  report the photochemistry of the two metal-metal-bonded complexes CpFe(CO)2Re(CO)3(α-diimine) (α-diimine=4,4′-dimethyl-2,2′-bipyridine (bpy′), pyridine-2-carbaldehyde N-isopropylimine (iPr-PyCa)) which are characterized by strongly allowed metal to ligand charge-transfer (MLCT) transitions in the visible region.

  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

  The complexes [Re(R)(CO)(3)(dmb)] (dmb = 4,4'-dimethyl-2,2'-bipyridine; R = CH3, CD3, Et, Bz, or iPr) were synthesized and their spectroscopic (H-1, and C-13 NMR, IR, UV-Vis, resonance Raman) properties were studied. According to the resonance Raman spectra the lowest-energy electronic transition has mainly MLCT character. It is therefore concluded that the (3)sigma(Re-R)pi*(dmb) state from which these complexes undergo homolysis of the Re-alkyl bond, is occupied by surface crossing from the nonreactive MLCT states. The [Re(CO)(3)(dmb)](.) radicals, formed by the homolysis reaction, were trapped by nitrosodurene and PPh3, and their adducts were identified with EPR spectroscopy. The thermal reactions of the radicals in different media were followed with IR spectroscopy. (C) 1999 Elsevier Science S.A. All rights reserved.
