developed a visible-light driven oxo-acyloxylation of aryl alkenes with carboxylic acids and molecular oxygen. A metal-free photoredox system, consisting of an acridinium photocatalyst, an organic base, and molecular sieve (MS) 4 Å, promotes chemoselective aerobic photooxidation of aryl alkenes. This approach may provide a green, practical, and metal-free protocol for a wide range of α-acyloxy ketones.
我们开发了可见光驱动的芳基烯烃与羧酸和分子氧的羰基酰氧基化反应。由metal啶光催化剂,有机碱和4Å分子筛组成的无金属氧化还原体系可促进芳基烯烃的化学选择性好氧光氧化。这种方法可以为多种α-酰氧基酮提供绿色,实用且不含金属的方案。
