[Chemical Properties]

Boron trifluoride acetonitrile complex is a colorless or light yellow transparent liquid, easily soluble in water, and miscible in various organic solvents such as alcohol and ether. It is mainly used as a catalyst for organic reactions. It is an important raw material for the preparation of boron halide, elemental boron, borane, sodium borohydride and other borides.
[reaction suitability]

core: boron
reagent type: Lewis acid
reagent type: catalyst
[Synthesis]

Boron trifluoride acetonitrile complex can be prepared by 20% oleum, boron anhydride and fluorite(9:1:3) were stirred at 130℃ and then poured into acetonitrile to give the complexation.
