Abstract

To protect and serve: The efficiency of Type I radical photoinitiators for acrylate polymerization is greatly increased by the presence of NHC‐boranes. Conversion of the initially photogenerated radicals, R. (see scheme), into strongly nucleophilic NHC‐boryl radicals, through hydrogen‐atom transfer, gives a better matched radical for subsequent reaction with monomer, ensuring better initiation.
