Abstract
AbstractAn unprecedented approach for the synthesis of homo‐ and hetero‐1,2,4‐triaryl benzenes has been developed using a simple base‐mediated reaction of either α‐aryl cinnamyl alcohols or α,γ‐di‐aryl propanones. The salient feature of this strategy involves the sequential hydride transfer, regiospecific condensation, regiospecific dearylation, and aromatization under metal‐free reaction conditions. The synthesis of unsymmetrically substituted triphenylenes by oxidative coupling of the synthesized 1,2,4‐triaryl benzenes has also been demonstrated.
