Claim:
1. A catalyst complex for a redox-based atom transfer radical addition reaction, an atom transfer radical coupling reaction or a controlled radical polymerization reaction, the catalyst complex comprising: a transition metal; and a ligand comprising from 2 to 6 heteroatom containing groups that bond to or chelate with a transition metal, wherein at least one of the heteroatom containing groups comprises a structure selected from a nitrogen containing heteroaromatic ring, wherein the heteroaromatic ring further comprises one or more electron donating substituents; wherein the ligand has a structure selected from the group consisting of (4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-bis(pyridin-2-ylmethyl)-amine (TPMA*-1), bis(4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-pyridin-2-ylmethyl-amine (TPMA*-2), tris[(4-methoxy-3,5-dimethyl)-pyrid-2-ylmethyl]amine (TPMA*-3), (4-methoxy-pyridin-2-ylmethyl)-bis(pyridin-2-ylmethyl)-amine (TPMA-OMe), bis(4-methoxy-pyridin-2-ylmethyl)-pyridin-2-ylmethyl-amine (TPMA-OMe-2), tris((4-methoxy)-pyridin-2-yl)methy)l-amine (TPMA-OMe-3), (4-(N,N-dimethylamino)-pyridin-2-ylmethyl)-bis(pyridin-2-ylmethyl)-amine (TPMA-NMe wherein the ligand forms the catalyst complex with the transition metal.
