Abstract

A free radical initiation(R-BR₂) system is based on a combination of an alcohol (R-OH) initiator and a dialkylborane (H-BR₂) activator. Due to an empty p-orbital in the B atom, the C-O bond can be cleaved to form a reactive C• radical for initiating radical polymerization, while the stable BR₂ radical remains inactive. Considering the large availability of various alcohol moieties, this asymmetric initiation chemistry can be applied to supermolecular structures and surface modifications.
