Cu -catalyzed cycloaddition reaction

Up to now, a variety of heterogeneous Cu-catalyzed cycloaddition reactions for the assembly of bioactive heterocycles have been reported. Most examples are the Huisgen-type 1,3-dipolar cycloadditions, but there are rare reports on the heterogeneous Cu-catalyzed synthesis of heterocycles through other types of cycloaddition reactions. 

It was shown that CNTs provide an excellent environment for Cu-catalyzed cycloaddition reactions [208]. The kinetics of reactions are accelerated and conversion rates improved in CNTs relative to catalysts deposited on the outer...
