A series of heteroleptic [Cu(phenantroline)(bisisonitrile)](+)-complexes was synthesized, and their structural, spectroscopic, and electrochemical properties were investigated. The new copper(I) complexes were employed as photoredox-catalysts in the visible-light-mediated atom transfer radical addition (ATRA). Especially, [Cu(dpp)(binc)]BF4 (6a-BF4) (dpp = 2,9-diphenyl-1,10-phenan-throline; binc = bis(2-isocyanophenyl) phenylphosphonate) proved to be highly active owing to an enhanced excited-state lifetime compared to the commonly employed [Cu(dap)(2)]Cl (1-CI)(dap = 2,9-di(p-anisyl)-1,10-phenanthroline). Furthermore, the catalyst could be applied to allylation reactions with trimethylallylsilane under mild visible-light photoredox conditions.
