Cooperative Catalysis of Primary and Tertiary Amines Immobilized on Oxide Surfaces for One-Pot C----C Bond Forming Reactions

D'you know what amine? Primary and tertiary amines are both immobilized on the same silica–alumina surface by silane‐coupling reactions. The resultant silica–alumina‐supported double‐amines are found to exhibit excellent catalysis for 1,3‐dinitroalkane synthesis from various aldehydes with nitromethane. A cooperative catalytic mechanism on the solid surface for this efficient synthesis is proposed.
