B2H6 Boron hydride

Diborane - bor- an n. B2H6 (boron hydride, boro-ethane). A colorless gas that has been used as a catalyst in the polymerization of ethylene. 

With this as introduction, let us now look at the individual steps in more detail for the case of hydroboration-oxidation of 1-decene. A boron hydride that is often used is dibomne (B2H6). Diborane adds to 1-decene to give tridecylborane according to the balanced equation ... 

Hydroboration can be carried out by using the boron hydride (B2H6) called diborane. 

The results suggest the possible addition reaction of O2 to a diborane-type intermediate in the primary step. Despite the fact that B2H6 is the simplest boron-hydride, there are a number of unanswered questions regarding the photochemical behavior of this molecule. 

Ammonia reacts with boron hydride to form a product with the empirical composition B2H6 2NH3 s2-is4) similarly, phosphine combines with diborane, in the gas phase above -30 °C and in the liquid phase in a sealed tube above -130 C, to give a white instable solid of constitution BH3PH3 (m.p. 32-35 °C) >is ). The dissociation pressure of BH3 PH3 is so large that the compound is already separated into its components at room temperature...

Diborane(6), B2H6. This spontaneously flammable gas is consumed primarily by the dectronics industry as a dopant in the production of silicon wafers for use in semiconductors. It is also used to produce amine boranes and the higher boron hydrides. Callery Chemical Co., a division of Mine Safety Appliances Co., and Voltaix, Inc., are the main U.S. producers of this substance. Several hundred thousand pounds were manufactured worldwide in 1990. 

Sodium borohydride reacts with Lewis acids in nonprotic solvents to yield diborane [19287-45-7], B2H6 (18), which can then be used to generate other useful organoboranes such as amine boranes, alkyl boranes, and boron hydride clusters. 

It is often necessary to introduce dopant atoms into the epitaxial (epi) layers. Typically, the dopant sources are hydrides (qv) of the impurity atoms. Common dopants are boron hydride, ie, diborane(6) [19287 45-7], B2H6, forp-type doping, and arsine [7784-42-1], AsH3, and phosphoms hydrides for -type doping (11). For example ... 

Boron Hydrides The boron hydrides, or boranes, are volatile, molecular compounds with formulas B Hm. The simplest is diborane (B2H6), the dimer of the unstable BH3. Diborane can be prepared by the reaction of sodium borohydride (NaBH4) and iodine in an appropriate organic solvent ...

The simplest boron hydride is borane, BH3, which dimerizes to diborane B2H6 in an equilibrium which lies overwhelmingly to the side of diborane under normal conditions of temperature and pressure (Equation B1.3). 

When magnesium is heated with boron, the product is magnesium boride, MgB2 (sometimes written as Mg3B2). The hydrolysis of the compound produces Mg(OH)2 and a boron hydride. Instead of the expected product of BH3, borane, the product is B2H6, diborane. 

The heteroboranes are derived ultimately from boranes, which, in turn, can be built up from lower molecular weight boron hydrides, the simplest of which is diborane, B2H6. There are a number of industrial processes described for the synthesis of diborane, most involving the reduction of boron trihalides with metal hydrides, as shown in equation (1). Other methods involve the reduction of trihaloboranes with group 1...
