—Ed. Borane tetrahydrofuran. Funding to support the advancement of the chemical sciences through research projects. 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. Borane–tetrahydrofuran (BH 3 –THF) is a charge-transfer complex that is a useful surrogate for diborane 1 in organic synthesis. In particular, it reacts violently with water to produce copious amounts of hydrogen. Now offered virtually. 15. The preparation of borane carbonyl, BH 3 (CO), played an important role in exploring the chemistry of boranes, as it indicated the likely existence of the borane molecule. It can be used to reduce carboxylic acids to alcohols or nitriles to primary amines.
