How do boron trifluoride ethers work?

Boron trifluoride ether complexes of Lewis acids play an important role in organic synthesis. To accomplish hydroxylation of double bonds, cleavage of epoxides, esterification of acids and many cyclization reactions, boron trifluoride ether complexes prove to be very useful compared to other Lewis acids.

 

What is bf3 et2o used for?

Boron trifluoride ether-ol is a very convenient reagent for the esterification of many para-aminobenzoic, aromatic, heterocyclic and unsaturated acids. In some esterification reactions, the use of this reagent provides higher yields compared to other reagents.

What is bf3 oet2?

Boron trifluoride etherate, strictly boron trifluoride diethyl etherate, or boron trifluoride-ether complex, is the chemical compound It is a colorless liquid, although older samples can appear brown.

 

What is bf3oet2?

Boron trifluoride diethyl etherate Synonym(s): Boron trifluoride ethyl etherate. Linear Formula: BF3 - O(C2H5)2. CAS No.: 109-63-7.

 

How is boron trifluoride etherate formed?

Preparation: BF3-OEt2 is prepared from BF3 by anhydrous ether; 1a BF3-MeOH complex is formed from BF3-OET2 and methanol. Purification: Oxidation in air darkens the commercial boron trifluoride ether complex; therefore the reagent should be redistilled before use.

 

How is boron trifluoride formed?

Boron trifluoride is a colorless gas formed by several reactions in which boron compounds come in contact with fluorinating agents. It is technically formed by the reaction of B2O3 with fluorite and sulfuric acid: B2O3 + 6HF → 2BF3 + 3H2O.

 

What is BF3 used for?

Boron trifluoride is a colorless gas with a strong odor that forms a dense white smoke in humid air. It is used as a catalyst for polymerization reactions, a flux and a fire extinguishing agent for optical fibers and magnesium.
