Gold(i) complexes with heteroaryl phosphine ligands

Author affiliations

Abstract

Gold(I) complexes ligated by phosphines with N-heterocycles in the periphery were prepared. First the synthesis of the ligands N-(diphenylphosphino)-4-(pyridin-2-yl)pyrimidin-2-amine (Hpypya) and N-(diphenylphosphino)-4-phenylpyrimidin-2-amine (Hphpya) are reported. These two compounds together with the related but earlier published ligands 3-(2-(diphenylphosphino)phenyl)-1H-pyrazole (Hph3py) and 5-(4-(diphenylphosphino)phenyl)-1H-pyrazole (Hph5py) were reacted with [(tht)AuCl] and [Au(tht)2]ClO4 to give the heteroleptic complexes [(L)AuCl] and the homoleptic compounds [(L)2Au]ClO4 (L = Hpypya, Hphpya, Hph3py, and Hph5py). Single crystal X-ray diffraction studies revealed that the heteroleptic complexes form hydrogen bonds between two N-heterocycles of neighboring complexes resulting in dimeric structures. The homoleptic complexes show a different behavior.
