【 摘 要 】

Indirect reductive amination of aldehydes, catalyzed by polymer supported triphenylphosphine-palladium acetate complex PS-TPP-Pd(OAc)₂ catalyst have been developed. The imine is prepared with molecular sieves in the first stage, followed by reduction with potassium formate catalyzed by PS-TPP-Pd(OAc)₂. The recovered catalyst could be reused for four consecutive cycles without loss in activity and provided an excellent yield of the desired products.
