Recent sulfinate esters chemistry is summarized in this feature article. Efficient methods to synthesize diverse sulfinate esters from readily available starting materials and various modern transformations of sulfinate esters are introduced.
A copper-catalyzed N–S bond coupling between hydroxylamines and sulfinic acids has been developed to access biologically active N-arylsulfonamides with operational simplicity, environmental friendliness and mild reaction conditions.
A photocatalytic three component cascade reaction of quinoxalinones, alkenes, and sulfinic acids toward sulfonated quinoxalin-2(1H)-ones under metal-, strong oxidant-, and external photosensitizer-free conditions was developed.
A water-soluble fluorinated triptycene backbone enables direct monitoring of generally unobservable intermediates arising in the reactions of thiols with oxidants such as H2O2, HOCl and 1O2.
This review comprehensively summarizes the dichalcogenative functionalization of unsaturated compounds over the past decade. The scopes, limitations and detailed reaction mechanisms are also discussed.
