Ruthenium-catalyzed coupling reaction of 2,3,5-trisubstituted furans with aryl halides through C–H bond cleavages
摘要:
A variety of functionalized furans were synthesized by way of a ruthenium-catalyzed coupling reaction of 2,3,5-trisubstituted furans with aryl halides through C-H bond cleavages. The feature of the reaction was facilitative preparation of furan derivatives good functional group tolerance. All reactions gave the desired products in moderate to good yields (56-89%) in the presences of [RuCl(2)(p-cymene)] and K(2)CO(3) in NMP at 120 degrees C. (C) 2011 Elsevier B.V. All rights reserved.
