Abstract
We carried out the research on the supported gold nanoparticles catalyzed aminolysis of ester with inert tertiary amine by C-O and C-N bond activations. Compared with homogeneous catalyst-Pd(OAc)2, the most outstanding feature of supported Au nanoparticles catalyst is their superior ability in catalyzing aminolysis reactions at room temperature. And the catalytic performance of AuNPs didn’t apparently decreased even after recycling five times. On the other hand, we carried out the research on the supported palladium nanoparticles catalyzed ortho-directed CDC reaction of alkylbenzenes and ortho-directed CDC reaction of aldehydes. It is found for the ï¬rst time that metallic state palladium, Pd0, can catalyze the ortho-directed CDC reaction of alkylbenzenes or aldehydes for the synthesis of aromatic ketones via a Pd0/PdII/PdIV catalytic cycle.
