Efficient Desulfinative Cross-Coupling of Heteroaromatic Sulfinates with Aryl Triflate in Environmentally Friendly Protic Solvents
摘要:
Aryl-substituted heteroaromatics were synthesized via desulfinative cross-coupling reactions using aryl triflate and heteroaromatic sulfinate coupling partners. This method uses synthetically versatile aryl triflates to access aryl-substituted heteroaromatics in good yields employing aqueous and alcoholic media without the use of base, additives or co-catalysts.

This letter describes the development of an environmentally benign palladium-catalyzedcross-coupling reaction using heteroaromaticsulfinates as nucleophilic coupling partners in aqueous media. This method accesses aryl-substituted heteroaromatics in very good yields chemoselectively without the need for base, additives or co-catalysts.
