The invention provides a method for synthesizing (E)-Alpha, Beta-unsaturated carbonyl compounds, which takes aldehyde and ketone as raw materials, takes organic stibium ion complexes containing bridged nitrogen atom ligand as a main catalyst, takes aliphatic amine as an auxiliary catalyst, carries out a catalytic reaction in a protic solvent, thus preparing the (E)-Alpha, Beta-unsaturated carbonylcompounds. The synthesis method inaugurates a new low-cost and green approach for preparing the (E)-Alpha, Beta-unsaturated carbonyl compounds and has the advantages that the raw materials have widesource, the selectivity and the yield of the target outcome approach to 100%, the catalyst can be used repeatedly, the reaction condition is simple, the reaction is easy for operation, the cost is lowand the preparation process is green and environment-friendly. |
