Abstract

Layered double hydroxide and Merrifield resin supported nanopalladium (0) catalysts are prepared by an exchange of PdCl42-followed by reduction and well characterized for the first time. The ligand-free heterogeneous layered double hydroxide supported nanopalladium (LDH-Pd0) catalyst using the basic LDH in place of basic ligands indeed exhibits higher activity and selectivity in the Heck olefination of electron-poor and electron- ...
