Aplicaciones

Boron trifluoride diethyl etherate is used as a Lewis acid catalyst in Mukaiyama aldol addition, alkylation, acetylation, isomerization, dehydrations and condensation reactions. It is involved in the prepattion of polyethers in polymerization reactions. As a catalyst, it is used in the preparation of cyclopentyl- and cycloheptyl[b]indoles and other diborane. It is also used in sensitive neutron detectors in ionization chambers as well as monitoring radiation levels in earth’s atmosphere.

Notas

Moisture sensitive. Store in cool place. Recommended to use under inet atomosphere. Incompatible with metals, acids, bases, alcohols, alkali metals, oxidizing agents and water. Reacts violently with water.
