Hagiwara H, Sugawara Y, Hoshi T, Suzuki T: 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. Chem Commun. 2005 Jun 21;(23):2942-4. Epub 2005 Jun 21. 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. |
