Heck reaction using nickel/TPPTS catalyst and inorganic base on supported ethylene glycol phase
The vinylation of butyl acrylate and halobenzene was studied using the Ni/TPPTS (TPPTS : triphenylphosphine trisulfonate, sodium salt) catalyst immobilized on silica. Inorganic base such as potassium acetate was found to be effective. The catalyst stability and recycle ability have been studied in the temperature range of 130-150 degrees C.
