Heterogeneously Catalyzed One-pot Synthesis of Aldimines from Primary Alcohols and Amines by Supported Ruthenium Hydroxides

摘要

The one-pot synthesis of aldimines from primary alcohols and amines via sequential reactions of alcohol oxidation and de-hydrative condensation could efficiently be promoted by supported ruthenium hydroxide catalysts, in particular Ru(OE)_x/ TiO2. The observed catalysis was truly heterogeneous and the retrieved catalyst could be reused without an appreciable loss of high catalytic performance.
