## Abstract The formation of methylene‐bis derivatives of benzopyran‐4‐ones from their Mannich bases was studied. On these grounds, unsymmetrical methylene derivatives have been synthesized by reacting Mannich bases of benzopyran‐4‐ones with structurally related compounds lacking the dialkylaminome
