Imines as a versatile organic synthetic intermediates have important applications in pharmaceuticals, dyes, and fine chemicals. In this work, heterogeneous Pd nanoparticles (Pd@N,O-carbon) on N doped carbon materials were developed using bamboo shoot as raw materials for highly efficient reductive coupling of nitroarenes with alcohols to selectively synthesize imines via the borrowing hydrogen strategy. The catalyst has obvious advantages in catalytic performance compared with other commercial catalysts or supports. Meanwhile, a broad set of complex imines were successfully synthesized in good yields with various functional groups tolerance for both nitroarenes and alcohols. This heterogeneous catalyst can also be recycled at several times without significant loss in activity and selectivity.

Key words: N doped carbon materials, Pd nanoparticles, nitroarenes, benzyl alcohols, borrowing hydrogen, imines
