Polymerization reactions using organic electron donors (OED) as initiators are presented herein. The metal-free polymerization of various activated alkene and cyclic ester monomers was performed in short times, under mild conditions, using small amounts of organic reducing agents and without the need for co-initiators or activation by photochemical, electrochemical or other methods. Hence, OED-initiators allow the development of an efficient, rapid and room temperature process, responding to energy-friendly, cost-efficient and secure technical specifications. Mechanistic investigations support an electron-transfer initiation pathway leading to the reduction of the monomer.
