Efficient one-pot syntheses of secondary amines from nitro aromatics and benzyl alcohols over Pd/NiTi-LDH under visible light

Abstract

Visible light-initiated one-pot syntheses of secondary amines from the reaction between nitro aromatics and alcohols are realized over Pd/NiTi-LDH via a successful coupling of LDH-based photocatalysis and Pd-based hydrogenation.

Solid Acid–Base Catalysts Based on Layered Double Hydroxides Applied for Green Catalytic Transformations

“…The Lewis acidic sites derived from LDH provide active sites for isomerization, while photocatalysis achieves selective cleavage of C-C bonds by regulating the generation of reactive oxygen species. Wang et al prepared Pd/NiTi•LDH nanocomposites by loading small Pd nanoparticles onto NiTi•LDH nanosheets for efficient one pot synthesis of secondary amines under visible light [69]. In previous studies, NiTi LDHs have been shown to exhibit excellent photocatalytic performance due to their abundant surface oxygen defects.…”
