Boron-oxygen

The presence of metal salts, particularly those containing alkaline-earth cations and/or haUdes, cause some shifts in the polyborate equiUbria. This may result from direct interaction with the boron—oxygen species, or from changes in the activity of the solvent water (63).

Polynuclear anions are formed by comersharing only of boron-oxygen triangles and tetrahedra in such a manner that a compact insular group results. 

The hydrated insular groups may polymerize in various ways by splitting out water this process may be accompanied by the breaking of boron-oxygen bonds within the polyanion framework.

The [2+4] eyeloaddition of dialkylaminobis(tiifluoromethyl)boranes (333) to methoxybutenone (0°C, pentane, 1 h) leads to nitrogen-boron-oxygen six-membered heteroeyeles 334 in 60% yield (90JOM253). 

Mechanistic studies have suggested that the TS involves bonding of Sc3+ to one of the boronate oxygens,57 which is consistent with the observation that the catalysts do not have much effect on the rate of allylic boranes. The phenyl substituent on the...
