文摘

Direct synthesis of diamines has been efficiently realized from the N-alkylation of amines with diols by means of heterogeneous bimetallic Pt¨CSn/¦Ã-Al₂O₃ catalyst (0.5 wt % Pt, molar ratio Pt:Sn = 1:3) through a ¡®Borrowing Hydrogen?strategy under ligand-free conditions. The present methodology provides an environmentally benign route to diamines.
