nature : boron and hydrogen compounds consisting of the name, also known as boron-hydrogen compounds. With the number of boron atoms, from gaseous to the liquid as solid. For example, under normal temperature diborane B2H6 for gas, small borane (10) B4H10 liquid, and decane borane (14) B10H14 was solid. Toxic! The volatile, flammable, water and air sensitive. Easy and Luis alkali formation of adducts unstable, and then there is no specific bifida or cracked. Borane is a cluster compounds, closed (Cage), open (nest-shaped) and net (spider web-shaped) structure of three basic types, respectively BnH2-n formula (n = 6-12), and BnHn BnHn +4 +6 . Closed for the integrity of the polyhedron, eliminating a peak into the net. The latter two were not complete, opening the polyhedron skeleton. Graphs were expressed B6H2-6 (closed), B5H9 (open) and B4H10 ( net) structure. The latter two were also missing electronic elements, more bonding. For example, open architecture and network, there are three centers-the two electronic boron-hydrogen - boron bond, some Boranes there three center-two electronic boron - boron - boron bond or other form of multi-center bond. In organic synthesis, diborane is an important reaction boron hydride reagents. Decane borane is silicone rubber vulcanization accelerator. Some boron-hydrogen BH-4 anions such as synthetic chemistry and chemical analysis were used to promote the curing agent. Boron phosphorus polymer with asbestos made of composite materials, high strength, and 600-700 ° C in the long-term use. Borane research on the development of vacuum technology in the chemical and application of structure and chemical bond theory has important significance. May BF3 and sodium borohydride reaction or by other borane from pyrolysis.
