Immobilization of Pd(OAc)(2) in ionic liquid on silica: application to sustainable Mizoroki-Heck reaction.
[reaction: see text] Palladium acetate was supported on amorphous silica with the aid of an ionic liquid, [bmim]PF(6). The immobilized catalyst was highly efficient in promoting the Mizoroki-Heck reaction without a ligand in n-dodecane for at least six reuses, in 89 approximately 98% yields. The TON and TOF reached 68 400 and 8000, respectively.
