Bis(silylene)‐Mediated N═N Bond Scission of Diazo Compounds

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
The carborane‐based bis(silylene) enables unprecedented N═N bond scission in diazodiarylmethanes. While xanthene‐ and aniline‐based scaffolds promote end‐on addition with partial N═N activation, the carborane‐based variant uniquely achieves complete N═N bond scission of Ar2C═N═N compounds, resulting in isolable disilicon nitride imino species.
