Title
H–Y zeolite is a versatile heterogeneous catalyst for the synthesis of β-nitroamines
Abstract

Heterogeneous aza-Henry reactions of aldimes with nitromethane were examined with zeolites as catalysts. Among the zeolite used, H–Y zeolite showed satisfactory catalytic activity for various aldimines, resulting in corresponding β-nitroamines in good yields. H–Y zeolite also showed the excellent reusability until the 3rd usage without loss of its activity; further, the calcination of deactivated H–Y zeolite allowed it to rejuvenate its catalytic activity. Solid-state 13C MAS NMR revealed the predominant activation of an aldimine into the H–Y zeolite.
