摘要

当使用高比例的底物/过氧化氢时,氧化铬(VI)诱导一个氧原子从t-BuOOH准定量转移到苯基亚甲基,相应的羰基化合物是主要的氧化化合物。叔苄基碳的主要反应是羟基化和叔丁基过氧化。在这些条件下,自由基的干扰是次要的反应途径。

Highly efficient oxygen transfer from tert-butyl hydroperoxide to benzylic carbons catalyzed by chromium(VI) oxide under high substrate/ hydroperoxide ratios

Chromium(VI) oxide induces a quasi-quantitative transfer of one oxygen atom from t-BuOOH to a benzylic methylene group when a high ratio of substrate/hydroperoxide is employed, the corresponding carbonyl compound being the major oxidation compound. Hydroxylation and tert-butyl-peroxidation are the main reactions observed for a tertiary benzylic carbon. The interference of free benzylic radicals under these conditions is a minor reactive pathway.
