Product Description of Boron Trifluoride Diethyl Etherate CAS#109-63-7
Boron trifluoride is a key Lewis acid catalyst in organic synthesis, widely involved in reactions such as polymerization, hydrocarbon processing, alkylation, and isomerization. Due to its difficulty in handling in gaseous form, it is commonly combined with polar oxygen- or nitrogen-containing compounds to form stable complexes, which can meet the activity requirements of various reactions. Boron trifluoride diethyl etherate is one of the most widely used complexes among these. Additionally, boron trifluoride can readily form complexes with thioethers, ketones, anisole, phenol, amines, and many of their derivatives, further expanding its applicability in organic synthesis.
