Boryl Anion Attacks Transition‐Metal Chlorides To Form Boryl Complexes: Syntheses, Spectroscopic, and Structural Studies on Group 11 Borylmetal Complexes

This is the authors' abstract. We don't add key points for this paper.

Nucleophilic borylation: Transmetalation from boryllithium compounds to Group 11 transition-metal chlorides gives the corresponding boryl complexes (see scheme). Borylsilver and borylgold complexes that have three-center-two-electron MB bonds are fully characterized for the first time. The NMR spectra and solid-state structures of the resulting boryl complexes reveal that the boryl ligand is one of the strongest known σ-donor ligands.
