Boron trifluoride etherate, strictly boron trifluoride diethyl etherate, or boron trifluoride–ether complex, is the chemical compound with the formula BF 3 O (C 2 H 5) 2, often abbreviated BF 3 OEt 2. It is a colorless liquid, although older samples can appear brown. The compound is used as a source of boron trifluoride in many chemical ...
The adduct with diethyl ether, boron trifluoride diethyl etherate, or just boron trifluoride etherate, (BF 3 ·O(CH 2 CH 3) 2) is a conveniently handled liquid and consequently is widely encountered as a laboratory source of BF 3. [15] Another common adduct is the adduct with dimethyl sulfide (BF 3 ·S(CH 3) 2), which can be handled as a neat ...
Reductions with hydrosilanes are methods used for hydrogenation and hydrogenolysis of organic compounds. The approach is a subset of ionic hydrogenation. In this particular method, the substrate is treated with a hydrosilane and auxiliary reagent, often a strong acid, resulting in formal transfer of hydride from silicon to carbon. [1]
An example of a dative covalent bond is provided by the interaction between a molecule of ammonia, a Lewis base with a lone pair of electrons on the nitrogen atom, and boron trifluoride, a Lewis acid by virtue of the boron atom having an incomplete octet of electrons. In forming the adduct, the boron atom attains an octet configuration.
Boron trifluoride etherate is also useful as an additive in reactions of higher-order cyanocuprates. The use of the 2-thienyl group as a "dummy" substituent in the cyanocuprate conserves the potentially valuable organolithium reagent used to generate the cyanocuprate (as only the dummy group is present in copper-containing byproducts).
BODIPY is the technical common name of a chemical compound with formula C. 9H. 7BN. 2F. 2, whose molecule consists of a boron difluoride group BF. 2 joined to a dipyrromethene group C. 9H. 7N. 2; specifically, the compound 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene in the IUPAC nomenclature. [1]
The central feature for the synthesis of the alkyl iodide fragment was the treatment of aldehyde to allenyltributylstannane in the presence of BF3-etherate to get the syn/syn isomer. Syn/anti methyl-hydroxyl-methyl stereotriads were obtained through the reaction between aldehyde and homochiral allenylzinc reagent.
The protic acid in the Scholl reaction is often an impurity in the Lewis Acid and also formed in the course of a Scholl reaction. Reagents are iron(III) chloride in dichloromethane, copper(II) chloride, PIFA and boron trifluoride etherate in dichloromethane, Molybdenum(V) chloride and lead tetraacetate with BF 3 in acetonitrile.
