Product Application of Boron trifluoride diethyl etherate CAS#109-63-7
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 earths atmosphere.Catalyst in the synthesis of polyol chains. Reagent for the coupling of imines to allylstannanes and 4′-nitrobenzenesulfenanilide to alkenes and alkynes.
Lewis acid reagent with broad application
Catalyst used in the preparation of cyclopentyl- and cycloheptyl[b]indoles from aryl cyclopropyl ketones via [3+2] cycloaddition.
