Abstract

Abstract: Recently developed routes to the synthesis of mono‐ and polyethynylated azulenes and their transformations into linear oligoazulenes with ethynyl and butadiynyl bridges as well as azulenyl‐substituted benzenes, cyclobutadiene complexes, and azulene‐substituted tetracyanobutadienes are reviewed. The utility of ethynylazulene derivatives for the synthesis of azulene‐substituted heterocycles has also been reviewed.
