Photoredox catalyst-mediated atom transfer radical addition for polymer functionalization under visible light

Abstract

A facile method for post-functionalization of polymers with side olefin groups was developed by visible light-mediated atom transfer radical addition (ATRA) employing a photoredox catalyst, fac-Ir(ppy)₃. In this work, various haloalkanes and α-halocarbonyls were introduced via post-modification into the polymer chains. This communication reports the first example of successful post-modification of polymers using a photoredox catalyst.
