Abstract:
The metal complexes [M{HB(hpp)}(2)(CO)(4)] (M = Cr, Mo or W) and [M(cod){HB(hpp)}(2)Cl] (M = Rh or Ir) of the doubly-base stabilized diborane(4) ligand [HB(hpp)](2) were fully characterized and their bonding nature was investigated in detail. While bonding in the group 6 complexes predominantly occurs through the hydrogen atoms, the metal-ligand interaction in the group 9 complexes can be regarded as an early stage oxidative addition of the boron-boron bond leading to diboryl compounds.

Hydroboration-Oxidation of Alkenes
Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.

Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared.
