In the past, borane molecules were often labeled "electron-deficient" because of their multicenter bonding (in which a pair of bonding electrons links more than two atoms, as in 3-center-2-electron bonds); this was done in order to distinguish such molecules from hydrocarbons and other classically bonded compounds. In 2018, the US Environmental Protection Agency reported that it was a low risk to human health and the environment, but this was disputed by a scientific advisory committee and environmental groups. The agency ordered manufacturer Sun Chemical and importer BASF to provide additional data concerning worker exposure. —Ed.

Alkyl- or arylboranes formed in this way can further react with unsaturated compounds such as olefins, imines, ketones, and alkynes (the hydroboration reaction) to make useful boron-containing intermediates. Average mass 85.940 Da. PubChem Substance ID 24850560. The electrostatic attraction between the components is not as strong as a covalent bond; but in many cases it is sufficient to make the complex behave as a covalent compound. Charge-transfer complexes such as BH3–THF form when a Lewis base (THF in this case) “donates” its unshared electron pair to an electron-deficient Lewis acid such as borane.
