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

Abstract
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.
