Diborane with water
Diborane reacts violently with water to form hydrogen and boric acid : B 2 H 6 + 6 H 2 O → 2 B (OH) 3 + 6 H 2 (Δ Hr = −466 kJ/mol = −16.82 kJ/ g) Diborane also reacts with alcohols similarly. Methanol for example give hydrogen and trimethylborate: [15] B 2 H 6 + 6 MeOH → 2 B (OMe) 3 + 6 H 2 Lewis acidity [ edit] See more Diborane(6), generally known as diborane, is the chemical compound with the formula B2H6. It is a toxic, colorless, and pyrophoric gas with a repulsively sweet odor. Diborane is a key boron compound with a variety of … See more Extensive studies of diborane have led to the development of multiple synthesis routes. Most preparations entail reactions of See more Diborane and its variants are central organic synthesis reagents for hydroboration. Alkenes add across the B–H bonds to give trialkylboranes, which can be further elaborated.
