Pyridylphosphine ligands continue to attract attention given their coordination behavior and potential use in multisite metal catalysts as they can coordinate early and late transition metals through multiple donors (P or N basic sites). However, functionalized pyridylphosphine(s), i.e., those containing substituted pyridines with additional donor/acceptor capability, have received limited attention. Here we present the synthesis of 6-pyrazole-pyridylphosphine ligands and their coordination behavior to Au(I), Cu(I) and Zn(II). The ability to coordinate to either or both P and N donor sites provides potential for multimetallic complexes.
