摘要: A new concept of simultaneous covalent anchoring a N-heterocyclic carbene palladium/ionic liquid matrix on the silica surface and application resulting catalyst in Heck reaction variety different haloarenes is described. The shows high thermal stability (up to 280 °C) could be recovered reused for four cycles, giving total TON ≅ 36 600. Furthermore, TEM coupled with EDX analysis indicate formation Pd nanoparticles within immobilized IL layer.
