Abstract

Chemistry Chemistry, Physical Physical Sciences Science & Technology
Polyisobutylene (PIB) oligomer-bound amines render Keggin polyoxometalates (POM) heptane soluble, making them efficient and recyclable catalysts for environmentally benign biphasic oxidations with hydrogen peroxide. This is illustrated using both oxidative desulfurization and alkene epoxidation reactions that can be efficiently carried out in a heptane-water two-phase system occurring through facile phase transfer of POM by the amine terminated PIB oligomer.
