Single-Step Thioetherification by Indium-Catalyzed Reductive Coupling of Carboxylic Acids with Thiols
摘要:
Direct thioetherification from a variety of aromatic carboxylic acids and thiols using a reducing system combined with InBr3 and 1,1,3,3-teramethyldisiloxane (TMDS) in a one-pot procedure is demonstrated. It was also found that a system combined with InI3 and TMDS underwent thioetherification of aliphatic carboxylic acids with thiols.
Indium-catalyzed reductive three-component coupling reaction of aliphatic/aromatic carboxylic acids with t-butyl mercaptan leading to unsymmetrical dialkyl sulfides
An InI3–TMDS (1,1,3,3-tetramethyldisiloxane) reducing system efficiently catalyzed a sequential three-component coupling of aliphatic carboxylicacids, aromatic carboxylicacids, and t-butyl mercaptan (t-butylthiol), to produce unsymmetrical dialkyl sulfides. With this reducing system, t-butyl mercaptan became a new source of sulfidation via an alkyl t-butyl sulfide that functioned as the reaction
