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

Unexpected photochemistry and charge-transfer complexes of [CB11H12]2 carborane [PDF]
, 2008 Although the [CB11H12]¯carborane does not exhibit an absorption band inUV, its triplet excited state can be generated upon 308 nm laser excitation; also unexpectedly carborane acts as electron donor forming a charge transfer complex with methylviologen ...
