• Catalytic hydrosilylation of olefins and ketones by base metal complexes bearing a 2,2′:6′,2″-terpyridine ancillary ligand

  olefins and silanes were also examined. In the hydrosilylation of ketones, unlike the hydrosilylation of 1-octene, all four complexes used in this study exhibited catalytic activity. Interestingly, in the reaction between diphenylsilane and acetophenone, the dominant product was the 1:2 double hydrosilylation product, not the 1:1 single hydrosilylation product, even in a reaction mixture of equal parts diphenylsilane

  在NaBHEt 3作为活化剂的情况下，研究了[M（tpy）Br 2 ]（M = Mn，Co，Ni或Cu）对烯烃和酮的氢化硅烷化的活性。[Co（tpy）Br 2 ]和[Ni（tpy）Br 2 ]显示出对1-辛烯与二苯基硅烷的硅氢加成反应的催化活性。特别是[Co（tpy）Br 2表现出良好的催化活性。线性的反马尔科夫尼科夫氢化硅烷化产物占主导地位。但是，也生产了少量的分支马尔可夫尼科夫产品。通过加入THF和吡啶作为溶剂，抑制了支链产物的产生。还检查了其他烯烃和硅烷的反应性。在酮的氢化硅烷化中，与1-辛烯的氢化硅烷化不同，本研究中使用的所有四种配合物均表现出催化活性。有趣的是，在二苯基硅烷和苯乙酮之间的反应中，即使在等份的二苯基硅烷和苯乙酮的反应混合物中，主要产物是1：2的双氢化硅烷化产物，而不是1：1的单氢化硅烷化产物。

  A series of complexes of 2,2′,2″-terpyridine (terpy) having the general formula M(terpy)X2 (M  Mn, Fe, Co, Ni; X  Cl, Br, I) have been prepared. X-ray powder patterns of these complexes have been obtained and compared with the patterns of several analogous zinc compounds which were previously shown to be penta-coordinate. It was concluded that all of these compounds, with the exception of Fe(terpy)Cl2

  制备了一系列具有通式M（terpy ）X 2（MMn，Fe，Co，Ni; X Br Cl，Br，I）的2,2'，2''-吡啶（叔丁基）的配合物。已经获得了这些配合物的X射线粉末图案，并将其与几种先前显示为五配位的类似锌化合物的图案进行了比较。可以得出结论，所有这些化合物（Fe（terpy）Cl 2除外）都是五配位的。此外，还报道了这些化合物的室温磁矩。这些化合物，除了Mn 2+以外，通常表现出明显高于仅自旋值的力矩。

  The isolation, structural characterization, and electronic properties of a series of high-spin mononuclear five-coordinated Mn(II) complexes, [Mn(terpy)(X)(2)] (terpy = 2, 2':6',2"-terpyridine; X = l(-) (1), Br- (2), Cl- (3), or SCN- (4)), are reported. The X-ray structures of the complexes reveal that the manganese ion lies in the center of a distorted trigonal bipyramid for complexes 1, 2, and 4, while complex 3 is better described as a distorted square pyramid. The electronic properties of 1-4 were investigated by high-field and high-frequency EPR spectroscopy (HF-EPR) performed between 5 and 30 K. The powder HF-EPR spectra have been recorded in high-field-limit conditions (95-285 GHz) (D much less than gbetaB). The spectra are thus simplified, allowing an easy interpretation of the experimental data and an accurate determination of the spin Hamiltonian parameters. The magnitude of D varies between 0.26 and 1.00 cm(-1) with the nature of the anionic ligand. Thanks to low-temperature EPR experiments, the sign of D was unambiguously determined. D is positive for the iodo and bromo complexes and negative for the chloro and thiocyano ones. A structural correlation is proposed. Each complex is characterized by a significant rhombicity with E/D values between 0.17 and 0.29, reflecting the distorted geometry observed around the manganese. Finally, we compared the spin Hamiltonian parameters of our five-coordinated complexes and those previously reported for other analogous series of dihalo four- and six-coordinated complexes. The effect of the coordination number and of the geometry of the Mn(II) complexes on the spin Hamiltonian parameters is discussed.
