Li~+-Catalyzed Radical Polymerization of Simple Terminal Alkenes

摘要

Uncatalyzed radical polymerization of unsubstituted alkenes is only effective for ethylene at high pressure and temperature,only produces low-molecular-weight oligomers of other alkenes,and has been eclipsed by transition-metal-catalyzed or cationic polymerization.Remarkably,in weakly ligating solvents under ambient conditions,Li~+ salts of highly alkylated derivatives of the monocarbadodecaborate anion 1 induce facile polymerization of terminal alkenes by the radical mechanism.
