Copper‐Catalyzed Synthesis of Sulfinic Esters via Oxidative Coupling of Thiols or Disulfides with Alcohols

The copper‐catalyzed coupling of thiols with alcohols was achieved under air atmosphere. The reaction proceeded smoothly in the presence of a base such as Cs 2 CO 3 or Rb 2 CO 3 affording sulfinic esters in good yields. Furthermore, disulfides were also available in the procedure. Both sulfide‐groups on disulfide were efficiently consumed.
