In this contribution we report the use of copper(I) homoscorpionate complexes TpxCu(I)(NCMe) as efficient catalysts for atom transfer radical reactions such as atom transfer radical addition (ATRA),1 atom transfer radical addition-cyclization (ATRA-C),2 atom transfer radical cyclization (ATRC)3 and atom transfer radical polymerization (ATRP).4 These studies have shown that changes in the substituents of Tpx ligands induce large differences in the catalyst activity of the TpxCu complexes toward those radical processes.(1) (a) Inorg.
