Шаблон:Chembox Boron trifluoride etherate, strictly boron trifluoride diethyl etherate, or boron trifluoride–ether complex, is the chemical compound with the formula BF3O(C2H5)2, often abbreviated BF3OEt2. It is a colorless liquid, although older samples can appear brown. The compound is used as a source of boron trifluoride in many chemical reactions that require a Lewis acid.[1] The compound features tetrahedral boron coordinated to a diethylether ligand.[2] Many analogues are known, including the methanol complex.

Reactions

Boron trifluoride etherate serves as a source of boron trifluoride according to the equilibrium:

BF3OEt2 Шаблон:EqmR BF3 + OEt2

The BF3 binds to even weak Lewis bases, inducing reactions of the resulting adducts with nucleophiles.[1]
