Abstract

A new synthetic procedure for the synthesis of 1,4,7-tribromo-10-methyltribenzotriquinacene on multigram scale is reported. Its conversion into 1,4,7-trimethoxy-10-methyltribenzotriquinacene is also described. Both procedures are simpler and greener alternatives to the known ones, and the crystal structures of both compounds are disclosed.

Key words

tribenzotriquinacene - convex molecules - radical bromination - single-crystal X-ray structural analysis - multigram synthesis
