Borane Tert-butylamine Complex
Borane ''tert''-butylamine is an amine borane complex derived from ''tert''-butylamine and borane. It is a colorless solid. The compound is prepared by the reaction of tert-butylammonium chloride and sodium borohydride:Girolami, G. S.; Rauchfuss, T. B. and Angelici, R. J., Synthesis and Technique in Inorganic Chemistry, University Science Books: Mill Valley, CA, 1999. :''t''-BuNH3Cl + NaBH4 → ''t''-BuNH2BH3 + H2 + NaCl In organic synthesis, borane ''tert-''butylamine can be used for selective reduction of certain functional groups including aldehydes, ketone In organic chemistry, a ketone is a functional group with the structure R–C(=O)–R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group –C(=O)– (which contains a carbon-oxygen double bo ...s, oximes, and imines. In photographic processing, it is used in the E-4 process, E-4 process, as "chemical enlighting" step in the processing of the fil ...

Amine Borane Complex
Ammonia borane (also systematically named amminetrihydridoboron), also called borazane, is the chemical compound with the formula H3NBH3. The colourless or white solid is the simplest molecular boron-nitrogen-hydride compound. It has attracted attention as a source of hydrogen fuel, but is otherwise primarily of academic interest. Synthesis Reaction of diborane with ammonia mainly gives the diammoniate salt 2B(NH3)2sup>+ (BH4)−. Ammonia borane is the main product when an adduct of borane is employed in place of diborane: :BH3(THF) + NH3 → BH3NH3 + THF Properties and structure The molecule adopts a structure similar to that of ethane, with which it is isoelectronic. The B−N distance is 1.58(2) Å. The B−H and N−H distances are 1.15 and 0.96 Å, respectively. Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. This difference is consistent with the highly polar natur ...
