Aerobic photooxidative cleavage of epoxides to carboxylic acids using magnesium bromide.

We developed an aerobic photooxidative cleavage of epoxides to carboxylic acids using a catalytic quantity of magnesium bromide and molecular oxygen as the terminal oxidant, under photoirradiation with a high-pressure mercury lamp.

Oxidative photodecarboxylation of α-hydroxycarboxylic acid derivatives with FSM-16 under visible light irradiation of fluorescent lamp.

Hydroxycarboxylic acids were converted to the corresponding carbonyl compounds under aerobic photo-oxidative conditions in the presence of FSM-16 under visible light irradiation by a fluorescent lamp. This synthetic protocol is the first example of FSM-16 functioning as a photocatalyst by visible light.
