Organoboranes are organic compounds of boron having one or more alkyl or aryl functional groups attached directly to the boron atom. Alkylboranes can be conveniently prepared by the addition of diborane, B2H6, to a carbon-carbon double or triple bond:...

The C-B bond has low polarity (the difference in electronegativity 2.55 for carbon and 2.04 for boron) and therefore alkyl boron compounds are in general stable though easily oxidized. Vinyl groups and aryl groups donate electrons and make boron less...
