Manganese‐Catalyzed Alkyl‐Heck‐Type Reaction via Oxidative Decarbonylation of Aldehydes

Abstract An alkyl‐Heck‐type cross‐coupling reaction is developed by manganese‐catalyzed oxidative decarbonylation of aldehydes. A variety of primary, secondary, and tertiary aliphatic aldehydes can participate in this alkenylation. The reaction is initiated by an alkyl radical, which is generated by oxidative decarbonylation of the aldehyde.
