Fusing triazoles: toward extending aromaticity
Organic Letters, 2011•ACS Publications
A novel method to extend aromaticity by one benzene and two triazole rings was developed
and optimized. This two-step route employs the copper-catalyzed azide–haloalkyne
cycloaddition reaction of an ortho-bis (iodoacetylene) system and the subsequent
intramolecular homocoupling fusion of the neighboring iodotriazoles, a process in which an
additional benzene ring is formed. This versatile methodology allows one to extend the core
size of chromophores and, consequently, to tune the material's properties.
