Reaction of diborane with oxygen
WebAmong the substances that react with oxygen and that have been considered as potential rocket fuels are diborane [B2H6 (g), which produces B2O3 (s) and H2O (g)], methane [CH4 (g), which produces CO2 (g) and H2O (g)], and hydrazine [N2H4 (l), … 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.
