Facile and green synthesis of α,β-unsaturated ketone catalyzed by air-stable organobismuth complex

摘要：

　　Air-stable cationic organobismuth complexes (2-5) possessing both acidic and basic characters were synthesized.The catalyst system that comprises an air-stable bifunctional Lewis acidic/basic organobismuth complex and BmimBF4 showed high catalytic activity,diastereoselec-tivity,stability,and reusability in the one-pot synthesis of (E)-α,β-unsaturat-ed ketones through highly selective crossed-condensation of ketones and aldehydes.Through switching the reaction from homogeneous to heterogeneous,the system shows facile separation ability and facile reusability.
