General description

Boron trichloride is a boron halide. It participates in the hydroboration of alkenes.[1] It forms strongly polarized donor-acceptor complexes with trimethyl- and triethylsilyl triflate.[2] Boron trichloride assisted reaction between acid chlorides and alkynyltrifluoroborate salts have been reported to form ynones.[3]

Application

Boron trichloride may be used in the synthesis of Cl-BODIPYs (BODIPY - Boron-dipyrromethene)[4] and tris(dimethylamino)borane.[5] It may be used in the synthesis of sceptrins and nakamuric acid.[6]
For preparing methyl esters of fatty acids and for transesterification of triglycerides.
