Formation of a Naphthalene Framework by Rhodium(III)-Catalyzed Double C-H Functionalization of Arenes with Alkynes: Impact of a Supporting Ligand and an Acid Additive

An efficient protocol has been developed for the synthesis of larger condensed arenes from aromatic hydrocarbons and internal alkynes. This protocol uses readily available [CpRhI2]nas a catalyst and Cu(OAc)2as an oxidant and proceeds smoothly through undirected double C-H activation. The addition of trifluoroacetic acid has a crucial positive impact on the reaction selectivity and the yields of the target products. In contrast to the previously reported catalytic systems, the new conditions allow the use of both dialkyl- and diarylacetylenes with the same high efficiency.

Rh/Cu-Catalyzed Cascade [4+2] Vinylic C?H O-Annulation and Ring Contraction of α-Aryl Enones with Alkynes in Air

An unprecedented Rh-catalyzed ketone-directed vinylic C?H activation/[4+2] O-annulation of α-aryl enones with internal alkynes followed by a Cu-catalyzed ring contraction in air to provide multiaryl-substituted furan derivatives has been developed. The preliminary mechanism study identifies the active pyrylium salt as the key intermediate.
