GENERAL DESCRIPTION AND APPLICATIONS |
||
| Borane (boron hydride) is any binary compounds of boron and hydrogen, which can be made from magnesium boride (MgB2) with the action of acid or can be prepared by the breaking apart of complex molecules into simpler products on heating in the presence of hydrogen. Boranes form interesting structures which cannot be described by the conventional two-electron covalent bond model. There are fewer electrons forming the chemical bonds than required in normal electron-pair bonds. An electron pair bonds both borons and the bridging hydrogen atom to create three atoms bond. The simplest is diborane (B2H6), highly reactive gas, used as fuels for air breathing engines and rockets and used in the synthesis of other organic boron compounds and metal borohydrides. Boranes are all reactive and oxidize readily in air. There is a wide range of boranes with shapes ranging from delicate spiders' webs to untidy birds' nests. There is also a wide range of borane derivatives containing other atoms, such as carbon and phosphorus. Carborane is any of a class of stable compounds containing carbon, hydrogen, and boron having general formula C2BnHn+2. Boranes are used as polymerization initiators (especially Trialkylboranes) for many monomers and chemo- or stereo-selective reductants. They convert aldehydes (chemoselective), ketones (stereoselective) to the corresponding alcohols in the manufacture of pharmaceuticals and other fine chemicals. They are used in the reductive alkylation of amines, novel metals and oximes. Boron Trifluoride is a very powerful Lewis acid which forms numerous chemical compounds. It is used as an agent for the surface treatment of steel and glass. It is a starting material for the production of active agents in pharmaceuticals and for the production of boranes and borates including tri (tetra) phenylborates. | ||
