13 mag 2024 · In this work, we present a new perspective on imidazolium dicyanomethylides with their synthesis and utilization as anionic N-heterocyclic carbenes (NHCs). The values of relative carbene formation energies (CREF) for a wide range of substituted imidazolium ylides unknown in the literature showed promising properties.

13 mag 2024 · Sean-Ray Kahnert, J. Namyslo, +2 authors. Andreas Schmidt. Published in Annalen der Pharmacie 13 May 2024. Chemistry. In the past, the use of nitrogen ylides focused primarily on cycloadditions, where the 1,3‐dipole was used as a building block for the formation of heterocycles such as pyrroles or pyrrolinones.
