Abstract: Dienophilic behaviour of nitrothiophenes and nitroselenophenes towards Diels-Alder reactions with dienes of medium nucleophilicity is studied under thermal conditions. While nitrated thiophenes reacted via Hetero Diels-Alder, nitrated selenophenes followed the normal process.
Keywords: nitrothiophenes, nitroselenophenes, Diels-Alder
