A transition-metal-free tandem reaction of β-arylethenesulfonyl fluorides and α-cyano-β-methylenones has been revealed. {In the|Within the|Inside the} presence of cesium carbonate, 2-arylethenesulfonyl fluorides react with α-cyano-β-methylenones {through|via|by means of|by way of} a tandem Diels-Alder cycloaddition/sulfur (VI) fluoride exchange/elimination {process|procedure|method|approach|course of action} to afford cyclohexadiene, which {further|additional} undergoes decyanolative aromatization in one-pot to {produce|create|generate|make} 1,{3|three},5-triarylbenzenes in moderate to {good|great|excellent|very good|fantastic|superior} yields. {In addition|Additionally|Furthermore|Moreover|Also}, direct oxidative aromatization of cyclohexadiene intermediate will construct {2|two},{4|four},6-triarylbenzonitriles.
