Yield: 74%

Steps:

1 EXAMPLE 1
EXAMPLE 1 Vinyl chloride (20.2 grams, 0.32 mole) and 99.8 grams (2.93 moles) of H2 S were condensed in a quartz tube equipped with a magnetic stirring bar. The sealed tube was irradiated with a high pressure mercury arc (70 W Hanau immersion lamp) for 15 hours at 17° C. After release of the excess H2 S, 31.1 grams of a yellow liquid was obtained. Gas liquid chromatography of the product mixture indicated 92 peak area percent of 2-chloroethanethiol and 8 peak area percent of β,β'-dichlorodiethyl sulfide. Distillation of the products afforded 23 grams (74% yield) of 2-chloroethanethiol, b.p. 62° to 63°/118 mm, and 5.6 grams (about 12% yield) of residual β,β'-dichlorodiethyl sulfide.
