Avenue to novel o-carboranyl boron compounds – reactivity study of o-carborane-fused aminoborirane towards organic azides

Abstract

Herein we report the reactivity study of o-carborane-fused bis(trimethylsilyl)aminoborirane towards three different types of organic azides, i.e., aryl, alkyl, and silyl azides. The reaction with ArN3 (Ar = 2,6-iPr2C6H4, 2,6-C6H3Cl2,...

A Pd-catalyzed route to carborane-fused boron heterocycles

“…Several previous studies have been dedicated to generating icosahedral carborane-fused 2D carbo- and hetero-cycles as extensions of the carborane scaffolds. 17 These systems are interesting as they can provide new insights into questions of electronic delocalization between 2D and 3D aromatic scaffolds and give rise to structurally new heterocyclic motifs. 18 However, all-boron-vertex-bound icosahedral carborane-fused heterocycles bearing vicinal B–N bonds are still not accessible so far.…”
