Pd/C as an Efficient and Reusable Catalyst for the Selective N-Alkylation of Amines with Alcohols

An efficient Pd/C-catalyzed synthesis of secondary amines involving C-N bond formation was achieved from amines and alcohols with H2O as the only byproduct. This common, green, commercial, and cheap catalyst was recycled five times in this sustainable, simple, and economic procedure.
