Condensation of Propan-2-one with Formaldehyde and Propane-2-thiol

10.1134/S1070363220040015

The research investigates the three-component condensation reaction of propan-2-one (acetone) with formaldehyde and propane-2-thiol in the presence of sodium hydroxide to produce various ?-keto sulfides. The study aims to determine the optimal conditions for forming different products, namely 4-[(propan-2-yl)sulfanyl]butan-2-one (1), 3-{[(propan-2-yl)sulfanyl)methyl]but-3-en-2-one (2), and 4-[(propan-2-yl)sulfanyl]-3-{[(propan-2-yl)sulfanyl)methyl}butan-2-one (3), by varying the amount of sodium hydroxide. The key findings are that the product ratio depends on the quantity of sodium hydroxide used. When the molar ratio of acetone : formaldehyde : propane-2-thiol : sodium hydroxide is 1 : 1 : 1 : 0.03, compound 1 is initially formed, which then transforms into compounds 2 and 3. Increasing the amount of sodium hydroxide to 0.4 mol results in a maximum conversion of propane-2-thiol to 99% within 5 hours, with bis-sulfide 3 being the major product. The study concludes that the formation of compound 2 involves an aldol condensation of compound 1 with formaldehyde, and compound 3 is produced via a base-catalyzed thia-Michael addition of propane-2-thiol to the C=C double bond of compound 2.
