Cyclic alkyl(amino)iminates (CAAIs) as strong 2σ,4π-electron donor ligands for the stabilisation of boranes and diboranes(4): a synthetic and computational study

Abstract

Singly and doubly cyclic alkyl(amino)iminate (CAAI)-substituted boranes and diboranes(4) were synthesised by halosilane elimination between a silylimine and halo(di)borane precursors. 11B NMR-spectroscopic studies show that the CAAI ligand is a...

A crystalline doubly oxidized carbene

“…We recently demonstrated that an acyclic carbene bearing two strongly donating N-heterocyclic imine (NHI) 8,31,32 substituents features exceptional nucleophilicity, enabling the dearomatization of a proximal inert arene ring 7 . We reasoned that the electron-rich nature of the bis(imino)carbene, coupled with its flexible acyclic framework is an ideal platform to access a doubly oxidized carbene.…”
