Abstract Palladium substituted in cerium dioxide in the form of a solid solution, Ce 0· 98 Pd 0· 02 O 1· 98 is a new heterogeneous catalyst which exhibits high activity and 100% trans- selectivity for the Heck reactions of aryl bromides including heteroaryls with olefins. The catalytic reactions work without any ligand. Nano-crystalline Ce 0· 98 Pd 0· 02 O 1· 98 is prepared by solution combustion method and Pd is in+ 2 state. The catalyst can be ...
