Waste Corn-Cob Cellulose Supported Copper Catalyst for Click and Aza-Michael Reactions
We prepared a highly active cellulose supported poly(amidoxime) Cu-catalyst 2 by the surface modification of waste corn-cob cellulose through graft copolymerization process (Scheme 1). The Cu-catalyst 2 was efficiently promoted the click reaction1 of organic azides and terminal alkynes including the...
