|Abstract:||A number of boronium ions with the general formula [R2BL2]+ (where L is a donor, such as an amine), some borenium [R2BL]+, and even borinium [R2B]+ ions have been synthesized and structurally characterized. In all these compounds, boron has a formal oxidation state of +III. In addition to the academic interest in the bonding properties in these species, some of them have found application as catalysts in polymerization or Diels-Alder reactions. Boronium cations are also efficient initiators for the dehydrogenation of ammonia-borane. The boron atom of the boronium ions is more or less tetrahedrally coordinated by the two substituents R (for example, amido groups) and two donor ligands L (such as pyridine). In contrast, uncoordinated borinium species, such as the (dimethylamido)(2,2,6,6-tetramethylpiperidino)boron cation, feature an almost linear NBN unit|
