摘要：

C-H/C-C functionalizations with oxymethylated bicyclopropylidenes were accomplished with an iron catalyst under external oxidant-free conditions. The combination of the unique reactivity of bicyclopropylidenes with a robust iron(II) catalyst enabled C-C cleavages in a chemoselective fashion, which allows for the synthesis of isoquinolones, free isoquinolones, or bispiro-fused isoquinolones. Mechanistic studies provided strong support for the C-C cleavage via beta-C elimination. A rare monoselective C-F/C-H bond functionalization of trifluoromethylarene was also observed.
