Synthesis of β‐Hydroxysulfides via Multi‐Component Cascade Hydroxysulfenylation of Styrenes with NH4SCN and Water under Transition‐metal‐free Conditions

Abstract Transition‐mental‐free multi‐component hydroxysulfenylation of styrenes with NH 4 SCN and water to from β ‐hydroxysulfides is established. The reaction mechanism proceeded via a domino reaction after a radical addition to 2‐phenylimidazo[1,2‐ a ]pyridines. This approach features a wide substrate scope and functional group compatibility, providing 34 compounds in acceptable yields.
