Product Description of Boron Trifluoride Diethyl Etherate CAS#109-63-7
Boron trifluoride is a widely utilized Lewis acid catalyst in organic synthesis and serves as an essential catalyst in various organic reactions, including polymerization, hydrocarbonization, alkylation, and isomerization. However, handling boron trifluoride in its gaseous form can be inconvenient during practical applications. To meet the activity requirements of different chemical reactions, boron trifluoride is commonly combined with polar compounds containing oxygen or nitrogen atoms, forming relatively stable complexes with excellent usability. One typical example is boron trifluoride diethyl etherate, a complex extensively applied in China. Furthermore, boron trifluoride can also react with thioethers, ketones, anisole, phenols, amines, and numerous related derivatives to produce various coordination complexes.
