Abstract
Heck vinylation reaction was studied using Pd(OAc)(2)/TPPTS catalyst system in supercritical carbon dioxide. The addition of co-solvents such as water and ethylene glycol significantly enhances the rate of reaction without le aching of Pd into the product phase. The reactants/products can be easily s eparated from the catalyst by simple phase separation and the catalyst can be recycled. (C) 1999 Elsevier Science Ltd. All rights reserved.
