A New Nanomagnetic Cobalt Catalyst for Copper-free Sonogashira Coupling Reaction in Water at Room Temperature

Abstract

Chitosan (CS), which is an N-deacetylated derivative of chitin, is an example of polysaccharide that is widely spread in living organisms. Surprisingly, chitosan have unique characteristics of the biomaterials; including the nontoxicity, biodegradability, environmentally friendly, renewability and abundance. ...
