  transition metal oxo complexes is a fundamental reaction in oxidative chemistry carried out by both biological and synthetic systems. This centrality has motivated efforts to understand the patterns and mechanisms of such reactivity. We have therefore thoroughly examined the C-H activation reactivity of the recently synthesized and characterized late transition metal oxo complex PhB ( tBuIm)3CoIIIO

  过渡金属氧配合物对 CH 的活化是生物和合成系统进行的氧化化学中的基本反应。这种中心性促使人们努力了解这种反应的模式和机制。因此，我们彻底检查了最近合成和表征的晚期过渡金属氧配合物 PhB (tBuIm)3CoIIIO 的 CH 活化反应性。该复合物缀合物的 p Ka 和 BDFEO-H 的精确值已通过实验确定，并提供对观察到的反应性的深入了解。还测量了该复合物与 9,10-二氢蒽之间反应的活化参数，并与之前的文献实例进行了比较。PhB(tBuIm)3CoIIIO 与各种氢原子供体的反应速率评估表明，该复合物的反应性取决于目标底物的 p Ka，而不是 BDEC-H。这一观察结果与许多其他过渡金属氧配合物的普遍引用的反应性范式背道而驰。PhB(tBuIm)3CoIIIO 对 CH 活化反应的实验和计算分析表明，这些过程的过渡态包含显着的质子转移特征。然而，额外的实验强烈表明该反应不是通过逐步过程发生的，从而得出结论：这种

  The new dihydrogen complexes trans-[MH(H-2)L(2)]BF4, L = P(C6H4-4-R)(2)CH2CH2P(C6H4-4-R)(2), R = CF3, M = Fe, Ru, and Os, R = CH3, M = Fe, R = OMe, M = Ru, are prepared by reaction of the dihydride complexes MH(2)L(2) With HBF4. The H-H bond length of the spinning H-2 ligand does not change significantly as a function of R (from CF3 to CH3 when M = Fe and from CF3 to OCH3 for M = Ru) according to H-1 NMR T-1 and (1)J(HD) measurements while there is a lengthening for the Os complexes. The rate constants for H atom exchange (reflecting the ease of homolytic splitting of H-2) increase with the increasing donor ability of R for a given metal as do the pK(a) values (reflecting a decrease in ease of heterolytic splitting). The electrochemical properties of some complexes MH(Cl)L(2) and MH(2)L(2) are reported. As expected H-2 acidity decreases as the parent hydride becomes easier to oxidize with this change in R (same M). The trend in dihydrogen pK(a) values as a function of the metal, Fe < Os < Ru, is distinctively different to the trend in pK(a) values of the dihydride complexes M(H)(2)(CO)(4), Fe < Ru < Os, and [M(C5H5)(H)(2)(PPh(3))(2)](+), Ru < Os, The high H-H bond energy of the RU(2+) complexes trans-[RuH(H-2)L(2)]BF4 is probably the reason why they are less acidic than corresponding Os2+ complexes. A consideration of the pK(a) values correctly indicated that a RuH(2)L(2)/[RuH(H-2)L(2)](+) mixture would be more effective at H/D exchange between D-2 and HO(t)Bu than the dihydrogen complex alone.
