A one‐step transformation of γ ‐ and δ ‐(spiro)lactones into γ , δ ‐ and δ , ε ‐unsaturated aldehydes with an excess of formic acid in the vapor phase over a supported manganese catalyst is described for the first time. The scope and limitations of this new reaction are shown with different lactones as substrate, and a mechanistic rationale is proposed.
