Significance

Commercially available red copper catalyzed the oxidation of benzylamines with molecular dioxygen in the presence of isoquinoline or 1,10-phenanthroline to give the corresponding benzonitriles (eq. 1) or dibenzylimines (eq. 2).


Comment

The SEM analyses of the catalyst before and after the reaction showed that the surface of the catalyst was roughened during the ­reaction to suggest leaching of copper.
