Push-pull triazenes derived from 1-(benzylideneamino)- and 1-(sulfonimido)-azolylidenes

Abstract

In-situ-generated neutral 1-(benzylideneamino)- and novel anionic 1-(sulfonimido)-azolylidenes react with organic azides to afford diverse classes of push-pull triazenes and triazene salts. The scope of the heterocyclic core and substituents at the N1 and N3 positions of NHC precursors together with the thermal properties of resulting compounds were examined. © 2013 American Chemical Society.
