A practical and convenient solvent-free iridium-catalyzed [2+2+2] cycloaddition of alpha,omega-diynes and alkynes to prepare fused arenes has been developed. The method has shown high efficiency as isoindolines, dihydroisobenzofurans and indanes have been synthesized in good to excellent yields.

Practical Solvent-Free Ruthenium Trichloride-Mediated Benzannulation Approach to Fused Functionalized Arenes
The solvent‐ and ligand‐free [2+2+2] ruthenium‐promoted cycloaddition of α,ω‐diynes and alkynes provides a facile and efficient strategy for the synthesis of substituted benzene‐derived systems. The search for the optimal reaction conditions revealed the unprecedented catalytic activity of ruthenium trichloride for benzannulation reactions and this atom‐economical process allowed the synthesis of fused

A new, efficient dynamic kinetic resolution (DKR) of secondary aromatic alcoholsusing self-made solid super acid TiO2/SO42- as a racemization catalyst was developed. Low-cost and easily produced TiO2/SO42- showed excellent racemization activity. When coupled with the lipase, Novozym 435, good biocompatibility was observed, and optically pure aromatic acetate (>99%) was obtained with a high yield.
