  钒氧代亚烷基配合物的合成及其在闭环烯烃复分解反应中的反应性

  摘要：

  Viimido 亚烷基已被用于涉及环烯烃的开环复分解聚合反应。然而，由于对乙烯的不稳定性，这些配合物在与无环末端烯烃的反应中的应用受到限制。实验和理论研究表明，未取代金属环丁烯的 β-氢化物消除是这些系统中的主要分解途径。在此，我们报告的第一催化活性V的合成氧代亚烷基，VO（CHSiMe 3）（PET 3）2氯，其显示出与已知的V催化剂中闭环复分解反应的各种末端烯烃最高报生产率。提出的 DFT 研究表明，β-氢化物消除明显不利于 V oxo 物种。

• Lewis acid adducts oxovanadium(V) alkyl and triphenylsiloxy complexes: synthesis, characterization, and reactivity toward ethylene

  日期：1993.3

  The reaction of triphenylsilanol with V(O)(CH2SiMe3)3(2) gives V(O)(CH2SiMe3)2(OSiPh3) (3), V(O)(CH2SiMe3)(OSiPh3)2 (4), and V(O)(OSiPh3)3 (5), each of which can be isolated in good yield under the appropriate reaction conditions. The reactions of 2-5 with Al(CH2SiMe3)3 produce dark maroon solutions. Multinuclear NMR data-especially O-17 and V-51 NMR data-indicate that the product formed in each case is a Lewis adduct derived from coordination of Al to the terminus of the VO group, suggesting that the oxo ligand is the most Lewis basic site in 2-5. Preliminary reactivity studies indicate that coordination of Al(CH2SiMe3)3 to the oxo ligand facilitates insertion of ethylene into the V-C bonds of 2-4.

  The subject invention provides catalytical compounds/complexes, compositions comprising such compound/complex, synthesis of the compounds/complexes, and methods of using such compounds/complexes as catalysts in, for example, carbon isotope exchange (CIE) on target bioactive molecules. Methods that allow CIE directly on drug candidates are of great importance to chemistry, biology, and medicine. Especially valuable are catalytic procedures that rely on a limited collection of available labeled materials. The instant method comprises converting a methyl group to terminal ═CH 2 utilizing transfer dehydrogenation catalysts to enable V-based olefin metathesis, followed by a hydrogenation step. The one-pot strategy allows the formal methylation/demethylation sequence and can be applied to an assortment of alkyl-containing compounds.
