## Abstract The Ag^+^‐induced α‐chloro‐aldonitrone/olefin reaction in polar solvents can proceed by substitution, thereby providing a method for the preparation of β, γ‐unsaturated aldehydes. Positional as well as configurational retention of the olefinic double bond are mechanistically significant
