| Abstract: | A way of synthesis of benzothiophenes, in the gas phase, employing a monosubstituted aromatic compound, carbon disulfide as sulfur source and a Kearby type aluminium orthophosphate as catalyst, has been studied. The best yields in benzothiophene (53%) were reached when vinylbenzene was employed, in a very selective reaction.
