new group of cyanodibenzo[1,4]dioxines have been synthesized by cyano-activated fluoro displacement reactions between cyanodifluorobenzenes and catechols in DMF at 130 °C in the presence of potassium carbonate. This route is exemplified by the synthesis of cyanodibenzo[1,4]dioxines from several substituted catechols. The reactions are virtually quantitative. Cyanodibenzo[1,4]dioxines were hydrolysed
