| Research Abstract |
An amphiphilic resin-dispersion of nanoparticles of platinum and palladium were developed which exhibited high catalytic activity in aerobic oxidation of a wide variety of alcohols in water with an oxygen or air atmosphere. A novel solid-phase 3D metal-organic coordination network catalyst was prepared via self-assembly from PdC12(CH3CN)2 and a trisphosphine hub with three flexible alkylchain linkers.
A novel solid-phase self-organized catalyst of palladium nanoparticles was prepared from PdC12 with main-chain viologen polymers via complexation and reduction. This insoluble nanocatalyst nano-Pd catalyst efficiently promoted a-alkylation of ketones with primary alcohols. A tightly convoluted polymeric phosphotungstate catalyst was prepared via ionic-assembly of H3PW12040 and poly (alkylpyridinium).
An oxidative cyclization of various alkenols and alkenoic acids was efficiently promoted by the polymeric catalyst. The pincer complexes bearing a plane coordination structure and functional substituents were prepared to realize stereoselective catalysis and supra complex formation.
