Visible-Light-Promoted Metal-Free Aerobic Oxidation of Primary Amines to Acids and Lactones

A unique metal-free aerobic oxidation of primary amines via visible light photocatalytic double carbon–carbon bonds cleavage and multi carbon–hydrogen bonds oxidation was observed. Aerobic oxidation of primary amines could be controlled to afford acids by using dioxane with 18 W CFL, and lactones by using DMF with 8 W green LEDs, respectively. A plausible mechanism was proposed based on control experiments. This observation showed direct evidences for the fragmentation in the aerobic oxidation of aliphatic primary amines.

Preparation of α-Acyloxy Ketones via Visible-Light-Driven Aerobic Oxo-Acyloxylation of Olefins with Carboxylic Acids

We 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 ?, 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.

Facile aerobic photooxidative oxylactonization of oxocarboxylic acids in fluorous solvents

We developed efficient aerobic photooxidative oxylactonizations of oxocarboxylic acids promoted by trifluoroacetic anhydride with molecular oxygen as the terminal oxidant in the fluorous solvent FC-72.
