A simple and general visible-light-mediated oxidation of organoboron compounds has been developed with rose bengal as the photocatalyst, substoichiometric Et3N as the electron donor, as well as air as the oxidant. This mild and metal-free protocol shows a broad substrate scope and provides a wide range of aliphatic alcohols and phenols in moderate to excellent yields. Notably, the robustness of this
已经开发了一种简单而通用的可见光介导的有机硼化合物的氧化方法,其中孟加拉红作为光催化剂,亚化学计量的Et 3 N作为电子给体,而空气作为氧化剂。这种温和且不含金属的方案显示了广泛的底物范围,并以中等至极好的收率提供了多种脂族醇和酚。值得注意的是,该方法的鲁棒性在有机硼化合物的立体有氧氧化中得到了证明。
