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

Synthesis, resolution and crystal structures of two enantiomeric rhodamine derivatives
Acta Crystallographica Section E: Crystallographic Communications, 2017 The title molecule, rac-6′-bromo-3′-diethylamino-3H-spiro[2-benzofuran-1,9′-xanthen]-3-one, C24H20BrNO3, was synthesized and the two enantiomers which formed were separated. The structures of all three compounds were determined and compared with those of
