The effective use of VIS is a most important research topic at this time of hoped-for development of new energy conversion and energy-using technology; however, there have been no reports about application of photo-oxidation with VIS by a general-purpose fluorescent lamp to fine chemistry. In the course of our study on photo-oxidation, we found that a combination of CBr4-Ph3P, a non-metal method, enables us to carry out aerobic photo-oxidation of alcohols to the corresponding carboxylic acids under irradiation of VIS from a general-purpose fluorescent lamp. Aliphatic primary- and secondary alcohols, benzyl alcohols generally afforded the carboxylic acids directly in good to high yield. Our new oxidation method is interesting due to non-use of metals and halogenated solvents, waste reduction, and use of molecular oxygen.
