Synthesis of β-hydroxysulfides via visible-light-driven and EDA complex-promoted hydroxysulfenylation of styrenes with heterocyclic thiols in EtOH under photocatalyst-free conditions

A convenient, environmentally friendly, visible-light-driven and EDA complex-promoted direct hydroxysulfenylation of styrenes under photocatalyst- and transition metal-free has been developed with O 2 as the oxygen source and EtOH as the solvent.
