ABSTRACT:
A process comprises contacting, in the presence of a catalyst, hydrogen sulfide or a mercaptan such as, for example, n-dodecyl mercaptan with an .alpha.,.beta.-unsaturated carbonyl or .alpha.,.beta.-unsaturated cyano compound such as, for example, methyl acrylate wherein the catalyst comprises a pyridine derivative such as, for example, 4-(dimethylamino)pyridine or an ion exchange resin such as, for example, "AMBERLYST A-21" to produce a 3-hydrocarbylthio derivative of the .alpha.,.beta.-unsaturated carbonyl or .alpha.,.beta.-unsaturated cyano compound such as, for example, methyl 3-(dodecylthio)propionate.
