Treatment of osmapentalyne [Os{≡C‐C( COOMe )= CH ‐C= CH ‐C( PPh 3 )= CH ‐}Cl( PPh 3 ) 2 ] + B F 4 − with arylamines in the presence of Cs 2 CO 3 produced osmium‐bridged polycyclic aromatic complexes. In this reaction, metal carbyne of osmapentalyne was first attacked by nucleophiles, followed by a C‐H oxidative addition. The UV ‐Vis spectra of these osmium‐bridged polycyclic aromatic complexes were measured. The result shows that these osmium‐bridged polycyclic aromatic complexes have broad absorption in the UV ‐Vis region up to 650 nm.
