Highly efficient hydroamination of phenylacetylenes with anilines catalysed by gold nanoparticles embedded in nanoporous polymer matrix: Insight into the reaction mechanism by kinetic and DFT investigations

The synthesis of aromatic ketimines via hydroamination of phenylacetylenes (PAs) with anilines (ANs) has been accomplished in high yields and with excellent regio- and stereo-selectivity using gold nanoparticles (AuNPs) embedded in crystalline syndiotactic polystyrene-cis-1,4-polybutadiene (sPSB) multiblock copolymer matrix. The performances of the AuNPs-sPSB catalyst exceed those of the other commercial gold catalysts as a result of the...
