TRIBUTYLBORANE Usage And Synthesis

Chemical Properties

Colorless pyrophoric fluid. Insoluble in water; soluble in most organic solvents.

Uses

Petrochemical industry, organic reactions, catalyst.

Uses

Tributylborane is a reducing agent used in the controlled radical polymerization of alkyl acrylates.

Synthesis Reference(s)

Tetrahedron Letters, 26, p. 4311, 1985 DOI: 10.1016/S0040-4039(00)98721-5

Hazard

Flammable, dangerous fire risk, store and use in inert atmosphere, ignites spontaneously in air.

Safety Profile

Poison by intravenous route. Moderately toxic by ingestion. A very dangerous fire hazard when exposed to heat or flame; can ignite spontaneously. When heated to decomposition it emits acrid smoke and irritating fumes. See also BORANES.
