Boronated Cyanometallates

open access: yesInorganic Chemistry, 2022
Fourteen boronated cyanometallates ([M(CN-BR3)6]3/4/5– (M = Cr, Mn, Fe, Ru, Os, R = BPh3, B(2,4,6,-F3C6H2)3, B(C6F5)3) have been characterized by X-ray crystallography and spectroscopy [UV-vis-NIR, NMR, IR, spectroelectrochemistry, and magnetic circular dichroism (MCD)]; CASSCF+NEVPT2 methods were employed in calculations of electronic structures. For (

Synthesis of Boron Analogues of Enamines via Hydroamination of a Boron−Boron Triple Bond [PDF]

open access: yesAngewandte Chemie International Edition, 2020
AbstractAn N‐heterocyclic‐carbene‐stabilized diboryne undergoes rapid, high‐yielding and catalyst‐free hydroamination reactions with primary amines, yielding 1‐amino‐2‐hydrodiborenes, which can be considered boron analogues of enamines. The electronics of the organic substituent at nitrogen influence the structure and further reactivity of the diborene
