A series of monopropargyl catechol derivatives synthesized via the Sonogashira coupling reaction were stereoselectively converted to (Z)-2-ylidene-1,4-benzodioxanes using FeCl3 as the catalyst, and structurally characterized by 1H NMR, 13C NMR and HRMS techniques.

Key words: iron catalysis, 1,4-benzodioxane, monopropargyl catechol, selective synthesis
