Azulenophenanthrenes from 2,2′-Di(arylethynyl)biphenyls through CC Bond Cleavage of a Benzene Ring

Azulenophenanthrenes from 2,2′-Di(arylethynyl)biphenyls through CC Bond Cleavage of a Benzene Ring

From six to seven: 2,2′‐Di(arylethynyl)biphenyls undergo a skeletal rearrangement in the presence of a platinum(II) catalyst to afford polycyclic aromatic compounds containing an azulene unit. The reaction involves CC bond cleavage of a benzene ring, which expands into a seven‐membered ring....
