Many experimental and theoretical studies have now contributed to the understanding of the classical metal-boron linkage in borylene complexes. Future work could probably envisage possible applications of those species, especially if one considers their close relationship to carbonyl or carbene complexes and their potential in stoichiometric or catalytic reactions.
