The borylene–carbonyl moiety in [bis (silylene) B (CO)][WBr (CO) 5] shows diverse reactivity.
Reduction, migration, and complete cleavage of CO have been observed at the boron …

Borylenes (BÀR) are highly reactive species that have only been observed at low
temperatures [1] or their presence inferred from the products of trapping reactions.[2] The …

Walter Hieber s seminal work on metal carbonyl compounds not only established these
complexes as one of the most important classes of organometallics, but also disclosed …

The chemistry of borylene complexes has significantly developed over the past few years,[1]
and based on a more detailed understanding of the bonding situation of BR ligands, it is well …

The study of transition-metal complexes of boron has become an area of widespread
