Abstract

original image

The new anionic heterocycleimidNHC (4,6-dioxo-1,3,5-triazin-2-ylidene-5-ide), combining a carbene and an anionic imidate, was readily prepared through a coupling reaction between 1,3-dimesityl formamidine and N-phenoxy carbonyl isocyanate followed by deprotonation. The donor properties of this switchable ligand were determined, whereas its ambidentate nature was established through the directed construction of exotic stacked polymetallic architectures.
