One-pot consecutive catalysis by integrating organometallic catalysis with organocatalysis.

Abstract

The present study integrates two types of catalysis, namely, organometallic catalysis and organocatalysis in one reaction pot. In this process, the product of the first catalytic cycle acts as catalytic component for next catalytic cycle. The abnormal N-heterocyclic carbene-copper-based organometallic catalyst acts as an efficient catalyst for a click reaction to provide triazole, which, in turn, acts as an efficient organocatalyst for different organic transformations, for example, aza-Michael addition and multicomponent reactions, in a consecutive fashion in the same reaction pot.
