Sustainable Mizoroki-Heck reaction in water: remarkably high activity of Pd(OAc)(2) immobilized on reversed phase silica gel with the aid of an ionic liquid

Palladium acetate immobilized on reversed phase amorphous silica gel with the aid of an ionic liquid, [bmim]PF6, was highly efficient in the promotion of the Mizoroki - Heck reaction in pure water without a ligand up to the sixth re-use, in 95% average yield with TON and TOF 1,600,000 and 71,000 (h(-1)), respectively.
