Ene thiol reaction
In organosulfur chemistry, the thiol-ene reaction (also alkene hydrothiolation) is an organic reaction between a thiol (R−SH) and an alkene (R2C=CR2) to form a thioether (R−S−R’). This reaction was first reported in 1905, but it gained prominence in the late 1990s and early 2000s for its feasibility and wide range … See more Radical addition Thiol-ene additions are known to proceed through two mechanisms: free-radical additions and catalyzed Michael additions. Free-radical additions can be initiated by light, heat or radical … See more Initiation of cascade cyclization The thiol-ene reaction (and analogous thiol-yne reaction) have extensively been used in generating … See more • Click chemistry • Thiol-yne reaction • Off-stoichiometry thiol-ene polymer • Free-radical addition See more Click chemistry reactions are known to be high efficiency and have fast reaction rates, yet there is considerable variability in the overall reaction rate depending on the functionality of the alkene.
