Abstract
dl-[Ni(Phen)3]Cl2/Ag2CO3 assisted coupling of alkynes with 1,3-dicarbonyl compounds gave the corresponding substituted furans in good to excellent yields, and with good substrate scope. Beside the novel C�H functionalization and tandem coupling, the reaction also represents 100 % atomic economy. � 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
