P-450 and models thereof. Shilov's Ptsup II}-Ptsup IV} system appears attractive in that the species involved will tolerate Osub 2}, although catalytic oxidation has not yet been achieved; nor is much known about detailed mechanism or selectivity. In an attempt to further delineate the mechanism they have examined oxidation of water-soluble model substrates and report here unexpected findings of
在过去几年中,出现了许多有趣的例子,证明过渡
金属配合物通常在非常温和的条件下激活
烷烃中的 CH 键。大多数研究的系统与 Osub 2} 不相容,Osub 2} 是获得热力学有利、经济可行的催化反应的最理想的助剂。此外,潜在产品(
醇类、烯烃等)通常比起始
烷烃更具反应性,这限制了可实现的产率。当涉及氢原子提取路线时,后者尤其成问题,如 P-450 及其模型。Shilov 的 Ptsup II}-Ptsup IV} 系统看起来很有吸引力,因为所涉及的物种将耐受 Osub 2},尽管尚未实现催化氧化;对详细的机制或选择性也知之甚少。
