Soluble amphiphilic tannin-stabilized Pd(0) nanoparticles: a highly active and selective homogeneous catalyst used in a biphasic catalytic system.

Homogeneous BT-stabilized Pd(0) nanoparticles are highly active for the biphasic hydrogenation of hydrophobic substrates because BT is an amphiphilic polymer that can form hydrophobic bonds with the organic phase, thus increasing the possibility of catalytic species to contact with hydrophobic substrates.
