Abstract

The H-atom transfer (HAT) from water to ketyl radicals, mediated by titanocene(iii) aqua-complexes, can explain the Ti(III)-promoted reduction of ketones in aqueous medium better than the conventional House mechanism. Moreover, we also report novel evidences supporting the existence of these titanocene(iii) aqua-complexes.

摘要

水中的 H 原子转移（HAT）到酮基自由基，由钛（III）配合物水合复合物介导，可以更好地解释 Ti(III) 在水介质中促进酮的还原，而不是传统的豪斯机制。此外，我们还报告了支持这些钛（III）配合物水合复合物存在的新证据。
