Description and Uses
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.
