An unprecedented copper-catalyzed intermolecular sulfur–sulfur bond insertion between aryldiazoacetates and benzenesulfonothioate has been successfully developed. Diverse α-disulfur functionalized esters were synthesized in good to excellent yields. The sulfur ylide formation and subsequent Stevens rearrangement are considered as the key steps for the discovered reaction.
