A modular approach for multicomponent synthesis of amidines using modified Scolecite

Article abstract of DOI:10.1016/j.apcata.2015.11.010

Copper exchanged Scolecite was successfully synthesized and used as an efficient, mild and recyclable catalyst for promoting multi-component synthesis of amidines from 4-toluenesulfonyl azide, phenyl acetylene and variety of substituted amines in THF at ambient temperature in good yields within short reaction time.
