Diborane, with the chemical formula B2H6, is a highly reactive and flammable inorganic compound composed of boron and hydrogen. It is one of the simplest boranes and is known for its pyrophoric and toxic nature.

Preparation and Properties of Diborane: Diborane is usually prepared by the reaction of boron trifluoride (BF3) with lithium hydride (LiH) or sodium borohydride (NaBH4):

4 BF3 + 3 LiH → 2 B2H6 + 3 LiF

2 NaBH4 + BF3 → B2H6 + 2 NaBF4

Diborane exists as a colorless, highly flammable gas at room temperature. It has a pungent and repulsive odor, reminiscent of rotting fish.

Uses of Diborane: Diborane has limited practical applications due to its extreme reactivity and hazardous nature. It has been used in the past as a rocket propellant, but its use in this regard has declined due to safety concerns and the availability of other, less hazardous propellants.

Diborane does find use as a reducing agent in certain organic synthesis reactions, where its powerful reducing properties are required.

Safety Considerations: Diborane is highly toxic, flammable, and reactive. It reacts violently with air, oxygen, and water, and can spontaneously ignite in air. Its reactivity with water leads to the release of flammable and toxic hydrogen gas, making it highly dangerous to handle.

Due to its hazardous nature, diborane should only be handled by experienced researchers in specialized laboratories with proper safety equipment and strict safety protocols. The use of diborane is subject to strict regulations, and proper safety measures must be followed to prevent accidents and protect against its potential hazards.

In most cases, the use of diborane is restricted to well-controlled laboratory research and industrial processes conducted by professionals who are familiar with its risks and proper handling procedures.
