Direct Dehydrogenation for the Synthesis of α,β‐Unsaturated Carbonyl Compounds

Abstract α,β‐Unsaturated carbonyl compounds are among the most fundamentally important functional compounds and are widely applied in synthetic chemistry, medical chemistry and material chemistry. Thus, their synthesis has attracted much attention of chemists. The dehydrogenation of two adjacent sp 3 C−H bonds can directly construct carbon‐carbon double bonds with high atom efficiency, and has been used for preparing unsaturated compounds as a powerful strategy. Herein, we highlight recent advances in the preparation of the valuable α,β‐unsaturated carbonyl compounds through α,β‐dehydrogenation. magnified image
