diarylmethanes were directly oxidized into diaryl ketones in 67%–98% yields. Additionally, various secondary alcohols were also transformed into the desired products in 48%–98% yields. Importantly, the catalytic system in the absence of any organic solvent, surfactant, or phase transfer agent, had a wide substrate scope and a high tolerance for various functional groups.
我们使用70%的叔丁基氢过氧化氢(TBHP)在水中开发了一种简单,高效的Cu(II)催化的二芳基甲烷和仲醇无配体氧化的二芳基甲烷和仲醇。一系列二芳基甲烷被直接氧化为二芳基酮,产率为67%至98%。此外,各种仲醇也以48%–98%的产率转化为所需的产品。重要的是,在不存在任何有机溶剂,表面活性剂或相转移剂的情况下,催化体系具有较宽的底物范围和对各种官能团的高耐受性。
