Structurally Constrained Stibenium: Metallomimetic C−Si Bond Activation

Angewandte Chemie, EarlyView.
A structurally constrained stibenium cation supported by a 2,6‐bis(o‐carborano)pyridine pincer‐type ligand was prepared, and its preliminary reactivity toward silanes was investigated. Remarkably, Si−C bonds in silanes undergo activation via an oxidative‐addition‐type process at the cationic Sb center.

Isolation of a Highly Reactive CBNC Heterocumulene via Azidoborylene Photolysis: Facile Access to a Crystalline Dioxaborirane

Angewandte Chemie, EarlyView.
Azidoborylene photolysis results in the isolation of a reactive C═B═N═C heterocumulene bearing an ambiphilic boron centre. Addition of 3O2 to this species results in the clean conversion to a unique example of a dioxaborirane. ABSTRACT Oxidation of the formal boron(0) complex MeCAAC2B in the presence of tetrabutylammonium azide leads to the formation ...
