摘要：

Oxidative coupling of 3,3',4,4'-tetrahexyloxybiphenyl and a benzene derivative using iron(III) chloride, followed by a reductive workup with methanol, provides an easy, versatile synthesis of unsymmetrically substituted triphenylenes. These molecules are essential requisites for the production of new discotic liquid crystals and include systems with alpha-substituents and other substitution patterns previously impossible to obtain.
