Organic syntheses via boranes

Organoboron chemistry or organoborane chemistry is the chemistry of organoboron compounds or organoboranes, which are chemical compounds of boron and carbon that are organic derivatives of borane (BH3), for example trialkyl boranes. . Organoboron compounds are important reagents in organic chemistry enabling many chemical transformations, the most important one called hydroboration. Reactions of organoborates and b… WitrynaSyntheses of Polyhedral Boranes. “… [8] They have been observed during the thermal decomposition of borohydrides.

WitrynaIn the more complex boranes not only B-H-B bonds, but also B-B-B 3c, 2e-bonds occur. In such a bond, three B-atoms lie at the corners of an equilateral triangle with their sp3 hybrid orbits overlapping at its center. One of the common properties of borons is that they are flammable or react spontaneously through air.
