Ga(OTf)3-Catalyzed Direct Substitution of Alcohols with Sulfur Nucleophiles
摘要:
It is reported that Ga(OTf)(3) catalyzes the direct displacement of alcohols with sulfur nucleophiles. The products are versatile intermediates that can be utilized in carbon carbon, carbon sulfur bond formation or used in modified Julia olefination reactions. The only byproduct generated is water.

A new and efficient method has been developed for the synthesis of thioethers from carboxylates and thiols. The reaction proceeds via a Fe(III)-catalyzed direct displacement of carboxylates from benzylic or allylic esters by heterocyclic thiols. Short reaction times, good to excellent yields of products, and few side reactions are the significant features of the new protocol.
