Synthesis of Aromatic Compounds by Catalytic CC Bond Activation of Biphenylene or Angular [3]Phenylene
抄録
<jats:title>Abstract</jats:title><jats:p>Substituted phenanthrenes and picenes were easily prepared by reaction of biphenylene or angular [3]phenylene with various alkynes in the presence of a catalytic amount of [IrCl(cod)]<jats:sub>2</jats:sub>/dppe (cod=1,5‐cyclooctadiene, dppe=1,2‐bis(diphenylphosphino)ethane). The reaction is based on CC bond activation of the cyclobutane ring. The reaction tolerates the presence of bulky groups on the alkyne, such as the ferrocene moiety. In addition, a catalytic system based on [RhCl(cod)]<jats:sub>2</jats:sub>/dppe enabled the, hitherto unreported, reaction of biphenylene with nitriles to provide phenanthridines.</jats:p>
