General Description

(1E)-prop-1-ene-1-thiol, also known as 1-propenyl mercaptan, is a chemical compound with the formula C3H6S. It is a colorless liquid with a strong, unpleasant odor, similar to that of garlic or onions. (1E)-prop-1-ene-1-thiol is commonly used in the food industry as a flavoring agent and preservative due to its sulfurous aroma. Additionally, it is used in the production of rubber and plastics, as well as in the synthesis of other organic compounds. It is also found naturally in certain foods, such as onions, leeks, and garlic, contributing to their characteristic smell and taste. Furthermore, (1E)-prop-1-ene-1-thiol has potential applications in the pharmaceutical industry for the development of drugs and medical treatments. However, exposure to high concentrations of this compound can be irritating to the eyes, skin, and respiratory system, so proper handling and ventilation are necessary when working with it.

Initiation of thermal reactions of sulfur compounds by dialkyl selenides

The use of diethyl selenide (20-40 mol %) as initiator in the gas-phase synthesis of thiophene from diethyl disulfide and acetylene increases the selectivity of the process and the yield of thiophene from 40 to 92%. As a result, this reaction becomes the most efficient preparative method for the synthesis of thiophene and also of selenophene which is formed in up to 70% yield. The complete conversion of both sulfur-and selenium-containing reagents is attained. Due to much different boiling points, thiophene and selenophene can readily be separated by rectification of the reaction mixture. Dialkyl selenides also initiate other thermal reactions of hydrogen sulfide and organic sulfides.

HIGH-TEMPERATURE ORGANIC SYNTHESIS XXXV. THERMAL REACTIONS OF DI(1-PROPENYL) SULFIDE

The thermolysis of dipropenyl sulfide in a flow-type system in an atmosphere of nitrogen at 450-540 deg C leads to propenethiol, thiophene, methylthiophenes, and 2-ethylthiophene.The formation of the thiophene derivatives results from intramolecular radical cyclization of the initial sulfide.Dimethyl selenide (5-10 mole percent) substantially accelerates the thermolysis of dipropenyl sulfide, and the yield of 2-ethylthiophene at 450-480 deg C is increased appreciably.The high-temperature reactions of di(1-propenyl) sulfide with 2-halogenothiophenes and acetylene confirm that the propenethiol and thiophene derivatives are formed in parallel during the thermolysis of dipropenyl sulfide.
