Photocatalytic oxidative cleavage of styrenes using water and chlorides for application in rubber degradation
Abstract
A photocatalytic oxidative cleavage of styrenes, utilizing water as the oxygen source, has been reported. This protocol, which is metal- and oxidant-free, affords ketones in satisfactory yields and with good functional group tolerance. Critically, it achieves 96% degradation of isoprene rubber under mild conditions, thereby enabling sustainable polyolefin recycling.
