It is isomeric with the more symmetrical 2,5-dihydrothiophene. Both isomers of dihydrothiophene are colorless liquids with a thioether-like odor. In terms of their reactivity, both isomers exhibit characteristics of alkenes and thioethers, undergoing addition reactions at carbon and oxidation at sulfur. In contrast, thiophene engages in neither reaction. Dihydrothiophenes in nature 2,3-dihydrothiophene is present in dry fermented sausages, a product of the fermentation process. It has a nutty aroma.Corral Sara Leitner Erich Siegmund Barbara Flores Mónica Determination of sulfur and nitrogen compounds during the processing of dry fermented sausages and their relation to amino acid generation Food Chemistry January 2016 190 657–664 10.1016/j.foodchem.2015.06.009 10261/122206 free Dihydrothiophenes contribute to the aroma of the white truffle. The major component is 3-methyl-4,5-dihydrothiophene (alternative name:4-methyl-2,3-dihydrothiophene), produced by bacterial colonies in the truffle's fruiting bodies.Splivallo, R. Ebeler, S. E.
