General description

Potassium iodide catalyzed oxidative coupling of tert-butyl-N,N-dimethylaniline with indole has been investigated. It is an efficient polymerization accelerator.

Application

4-tert-Butyl-N,N-dimethylaniline was employed as amine initiator during free-radical/cationic hybrid photopolymerizations of acrylates and epoxides.
