Lambert, Romain; Wirotius, Anne-Laure; Vignolle, Joan; Taton, Daniel published the artcile< C-C couplings in water by micellar catalysis at low loadings from a recyclable polymer-supported Pd(II)-NHC nanocatalyst>, COA of Formula: C9H9Cl, the main research area is polymer supported palladium nanocatalyst micellar catalysis coupling reaction.
A specifically devised amphiphilic star-like polymer-supported Pd(II)-NHC2 unit (NHC = N-heterocyclic carbene) enables highly efficient micellar catalysis in pure water. An amphiphilic block copolymer carrying benzimidazolium moieties randomly distributed along the hydrophobic block is precisely synthesized by reversible addition fragmentation chain transfer (RAFT) polymerization Addition of Pd(OAc)2 followed by nanopptn. in water drives the metal-ligand coordination core-crosslinking reaction and the segregation of Pd-NHC2 units in the hydrophobic core to form robust polymeric micelles. This approach confers multiple advantages to both the Suzuki-Miyaura and Heck cross-coupling reactions, including robustness, almost no metal leaching, low catalyst loadings (0.1 mol% rel. to the substrate), easy recycling, very broad substrate scope and exceptionally high catalytic activity in water.
