摘要

A novel solid-phase catalyst of palladium nanoparticles, nano-Pd-V, was prepared from PdCl2 with main-chain viologen polymers via complexation and reduction. This insoluble nanocatalyst nano-Pd-V efficiently promoted α-alkylation of ketones with primary alcohols in the presence of Ba (OH) 2· H2O under atmospheric conditions without organic solvents. The nano-Pd-V catalyst was reused without loss of catalytic activity. Ring-opening alkylation of ...
