General description

Boron trichloride is a boron halide. It participates in the hydroboration of alkenes. It forms strongly polarized donor-acceptor complexes with trimethyl- and triethylsilyl triflate. Boron trichloride assisted reaction between acid chlorides and alkynyltrifluoroborate salts have been reported to form ynones.

Boron trichloride solution is used as a Lewis acid catalyst in the synthesis of BN-phenanthrenes.

Application

Boron trichloride may be used in the synthesis of Cl-BODIPYs (BODIPY - Boron-dipyrromethene) and tris(dimethylamino)borane. It may be used in the synthesis of sceptrins and nakamuric acid.
For preparing methyl esters of fatty acids and for transesterification of triglycerides.

Packaging

The 25 mL Sure/Seal bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
