How is 3-(Methylsulfanyl)-1-propene (CAS: 10152-76-8) typically synthesized?

3-(Methylsulfanyl)-1-propene is usually synthesized via the hydration of vinyl methyl sulfide or by the Wittig reaction with methyl vinyl ketone. Common catalysts include strong acids, and the process typically yields around 85-90% of the desired product. The method involves controlled temperature and pressure conditions to ensure high purity and selectivity.
