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 MB 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.
