gem-dibromomethylarenes: A convenient substitute for noncommercial aldehydes in the Knoevenagel-Doebner reaction for the synthesis of α,β-unsaturated carboxylic acids

(Chemical Equation Presented) A facile synthesis of α,β- unsaturated carboxylic acids from gem-dibromomethylarenes is described. gem-Dibromomethylarenes are employed for the first time in the Knoevenagel-Doebner reaction as aldehyde equivalents for the efficient synthesis of α,β-unsaturated carboxylic acids.
