Fluoroaromatics from arylamines. A convenient one-pot conversion using nitrosonium tetrafluoroborate was written by Milner, David J.. And the article was included in Synthetic Communications in 1992.Formula: C10H11FO2 This article mentions the following:
A simple, novel and extremely versatile procedure has been identified for the conversion of arylamines into the corresponding aryl fluorides. The amine is treated with nitrosonium tetrafluoroborate in dichloromethane and the resulting diazonium tetrafluoroborate is heated, without isolation or drying, to give the fluoroarom., generally in good yield. The method is applicable even to arylamines bearing carboxyl and hydroxyl substituents, which give poor yields of aryl fluorides under Balz-Schiemann conditions. In the experiment, the researchers used many compounds, for example, Ethyl 2-(4-fluorophenyl)acetate (cas: 587-88-2Formula: C10H11FO2).
Ethyl 2-(4-fluorophenyl)acetate (cas: 587-88-2) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Formula: C10H11FO2
