title: Two-Step Synthesis of Fluorescent 3-Arylated 1,3a,6a-Triazapentalenes via a Three-Component Triazolization Reaction.
abstract: Novel 3-arylated 1,3a,6a-triazapentalenes were synthesized using a metal-free three-component triazolization reaction followed by a triflate based cyclization step. This method starts from simple commercial starting materials and provides an easy functionalization strategy for the 3-position of the triazapentalenes. By introducing electron-withdrawing groups onto this position, stable and highly fluorescent dyes could be synthesized.
