dihydroisobenzofuran derivatives has been developed through the application of a halogen‐bridged iridium(III) complex to the [2+2+2] cycloaddition of α,ω‐diynes with alkynes. The cycloaddition tolerates a broad range of substitution groups, such as alcohol, alkyl, ether, and halogen, and the chemistry can be extended to prepare the corresponding borylated fused arenes. The reaction shows that hindered

Iridium(III) catalysis provides a convenient and general method for the synthesis of isoindolines via [2+2+2] cycloaddition reactions of diynes and alkynes. The reaction proceeds smoothly in environmentally benign and non‐distilled isopropyl alcohol, providing highly functionalized aromatic compounds in moderate to excellent yields.
