Description

Items	Specifications
Product name	Boron trifluoride diethyl etherate
CAS	109-63-7
Appearance	LIQUID
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 earths atmosphere.
Application	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.
Physical properties	Fuming liquid; stable at ambient temperatures but hydrolyzed on exposure to moist air; density 1.125 g/mL; refractive index 1.348; solidifies at -60.4°C; boils at 125.7°C; flash point (open cup) 147°F (68.8°C); decomposes in water.
Preparation	Boron trifluoride etherate is prepared by the reaction of vapors of boron trifluoride with that of anhydrous diethyl ether: BF₃ (g) + (C₂H₅)₂O (g) → (C₂H₅)₂O?BF₃.
General Description	Boron trifluoride etherate is a fuming liquid. Boron trifluoride etherate may be corrosive to skin, eyes and mucous membranes. Boron trifluoride etherate may be toxic by inhalation. Upon exposure to water Boron trifluoride etherate may emit flammable and corrosive vapors. Boron trifluoride etherate is used as a catalyst in chemical reactions.
Reactivity Profile	Boron trifluoride diethyl ether complex is a stable, highly flammable, colourless to brown fuming, corrosive liquid with a sharp pungent odour. It forms explosive peroxides in contact with air or oxygen. It reacts exothermically with water to form extremely flammable diethyl ether and toxic, corrosive boron trifluoride hydrates. The chemical is incompatible with bases, amines, and alkali metals. It immediately gets hydrolysed by moisture in air to form hydrogen fluoride. Boron trifluoride diethyl ether has applications in chemical laboratory as a catalyst in chemical reactions.
