| Research Abstract |
We have already developed gold nanocluster and bimetallic cluster catalysts immobilized on polystyrene-based polymer(PI-Au, PI-Au/M) and on carbon black-stabilized polymer(PI/CB-Au, PI/CB-Au/M), and found that these catalysts mediated aerobic oxidation of alcohols and so on. In this research, we have newly developed direct oxidative ester formation reactions from alcohols and one-pot aerobic oxidation-Michael reaction between allylic alcohols and 1, 3-dicarbonyl compounds. We have also realized aerobic oxidative amidation reaction from alcohols and amines using newly developed bimetallic catalysts of gold and iron-group metals(PI/CB-Au/Ni,-Au/Co,-Au/Fe). In addition, we have developed oxidative benzoxazole and benzothiazole synthesis from Schiff bases composed of o-aminophenols and aldehydes. These heterocycles could be obtained from N-alkyl-o-aminophenols through three step reactions including two aerobic oxidation steps in one-pot.
