A solid-phase self-organized catalyst of nanopalladium with main-chain viologen polymers:: α-Alkylation of ketones with primary alcohols

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