The photoinduced electron transfer reactions of acylphosphine oxide type photoinitiators with Cu(II)Cl-2/N,N,N',N '',N ''-pentamethyldiethylenetriamine complex for both atom transfer radical polymerization and copper catalyzed azide-alkyne cycloaddition processes is investigated by laser flash photolysis. The photolytically generated phosphonyl radicals are effective in reducing Cu(II) salts to Cu(I) with rate constants of similar to 2 x 10(9) M-1 s(-1). (C) 2014 Elsevier Ltd. All rights reserved.
