摘要：

Palladium nanoparticles supported within hybrid organic-inorganic foams have been generated The as-synthesized catalysts labeled Pd@gOrgano-Si(HIPE) (high internal phase emulsion) have been tested with or without addition of triphenylphosphine (PPh3) considering both the Suzuki-Miyaura and Mizoroki-Heck coupling reactions Particularly the catalysts Pd@gMercapto-Si(HIPE)-P4 and Pd@g3Amino-Si(HIPE)-P4 under addition of (PPh3) in a molar ratio 4 1 relative to palladium are offering good yields turnover and cycling performances for the Mizoroki-Heck coupling reaction (C) 2010 Elsevier B V All rights reserved
