Abstract: Rhodium(iii)-catalyzed C-C coupling of heteroarenes and fluorinated α-diazo diketones has been realized for the facile synthesis of 3-arylchromones. The reaction proceeds via chelation-assisted C-H activation, carbene insertion, and uncatalyzed intramolecular nucleophilic aromatic substitution, with C-F… read more here.
