Selanyl and tellanyl electrophiles as a driving force in the construction of sophisticated polyaromatic hydrocarbons

Abstract

Herein, we report the first examples of N-polyaromatic compounds bearing up to 13 fused aromatic rings, including 23H-benzo[12,1]tetrapheno[8,9-b]benzo[12,1]tetrapheno[9,8-h]carbazole derivatives. The reaction of selanyl and tellanyl electrophiles with ethynyl biphenyls through 6-endo-dig closure allows construction of N-polyaromatics in a simple one-pot process under mild reaction conditions in excellent yields.
