Hydrolysis- diborane is easily hydrolyzed by water to form boric acid. B 2 H 6 + H 2 O → 2H 3 BO 3 + 6H 2. Diborane upon treatment with lewis bases undergoes cleavage and forms borane which again reacts with lewis base to produce adducts. simon thelwall-jones

WebApr 12, 2024 · My initial reaction to this new professional challenge was to locate a book devoted to inorganic chemistry and find a description of the boron hydrides. I learned that the boron hydrides, such as diborane and decaborane, were toxic and readily flammable. Decaborane was stable while diborane would explode spontaneously if exposed to air. WebThe reaction of highly Lewis-acidic tetra(o-tolyl)diborane(4) with CO afforded a mixture of boraindane and boroxine via the cleavage of the CΞO triple bond. ¹³C-labeling experiments confirmed that the carbon atom in the boraindane stems from CO. simon thelwell haveringWebApr 7, 2015 · The compound diborane (B2H6) was at one time considered for use as a rocket fuel. Its combustion reaction is B2H6 (g) + 3 O2 (l) → 2 HBO2 (g) + 2 H2O (l) The fact that HBO2, a reactive compound, was produced rather than the relatively inert B2O3 was a factor in the discontinuation of the investigation of the diborane as a fuel. simon the likeable
