A novel kind of ferrocene moieties containing palladacycle catalysts 1 and 2 was synthesized and applied to Heck reaction. It was characterized by a wide variety of substrates, mildness of reaction conditions, freedom from protection of inert gases and high catalytic activity retainable after repeated uses. When catalyst 2 was used to catalyze the coupling ofiodobenzene with butyl acrylate, optimal results were obtained with 7 360 000 turnover number and 92% yield. The catalyst 2 could be reused at least five times in the coupling of iodobenzene with ethyl acrylate. Some of the reactions were followed by HPLC.
