Abstract

Abstract A series of cyclometallated gold (III) complexes [Au (equation image) Cl 2] 1a–l (H equation image= arylpyridines) and a PEG-linked complex 1m were synthesized. Complexes 1a–m are effective in catalyzing the synthesis of propargylic amines, chiral allenes and isoxazoles. Six-membered ring cyclometallated gold (III) complexes 1f–l exhibited higher catalytic activity than five-membered ring cyclometallated gold (III) ...
