1. The free-radical-induced addition of hydrogen sulfide to N-vinyl lactams was studied, and it was shown that sulfides and thiols can be prepared from N-vinylcaprolactam and 1-vinyl 2-pyrrolidinone in this way in overall yields of 75–85 %. 2. It was shown that the second stage of the process is the faster, so that the sulfide is preferentially formed. Synthesis of the thiol from N-vinylcaprolactam in 40–45 to yield was effected by the use of an 11–13-fold molar excess of hydrogen sulfide.
