Pd catalyzed insertion of alkynes into cyclic diaryliodoniums: A direct access to multi-substituted phenanthrenes

Cyclic diaryliodoniums remain unexplored compared to linear iodoniums. In our current work, internal alkynes were for the first time applied to react with cyclic iodoniums, catalyzed by Pd, resulting in a [4 + 2] benzannulation. Our work offers a new strategy to synthesize multi-substituted phenanthrene derivatives which are not easily accessed by conventional methods.

One-pot synthesis of diarylmethylidenefluorenes and phenanthrenes by palladium-catalyzed multiple C-H bond functionalization

Chemical equation presented A palladium-catalyzed rapid synthesis of diarylmethylidenefluorenes and phenanthrenes by multiple C-H bond activation, C-C bond formation, and Heck-type cyclization is described (see scheme).
