Photochemical C–H oxygenation of side-chain methyl groups in polypropylene with chlorine dioxide†
Abstract
The chlorine dioxide radical (ClO2˙) was found to act as an efficient oxidizing agent for the aerobic C–H oxygenation of the side-chain methyl groups in polypropylene under photoirradiation and ambient conditions (298 K and 1 atm). The oxygenated side-chain methyl groups were selectively converted to carboxylic acid and hydroxy groups.
