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

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