Abstract

New hexameric cyclophenylene-ethynylenes (CPEs, 1) were synthesized by alkyne metathesis of metadipropynylated benzenes. Treatment of one of these CPE derivatives (R¹> = tert-butyl, hexyl, dodecyl; R²= H, methyl) with [Os₃(CO)₁₀-(MeCN)₂] led to a decacarbonyltriosmium-CPE complex in which the planarity of the ring was significantly disrupted, as evidenced by the results of the single-crystal X-ray diffraction analysis.
