Description

It is used as a pharmaceutical intermediate. he reaction of 2?-substituted biphenyl-2-carboxylic acids (where the 2?-substituent is H, CO2H, NO2, Cl, OMe, or CO2Me) with lead tetra-acetate in refluxing benzene solution, under a nitrogen atmosphere, affords 3,4-benzocoumarin as a major organic product.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Il est utilisé comme intermédiaire pharmaceutique. Il réagit avec les acides 2′-biphényl substitué-2-carboxyliques (où le 2′-substituant est H, CO2H, NO2, Cl, OMe ou CO2Me), avec du tétra-acétate de plomb dans une solution de benzène de reflux, sous atmosphère d’azote, il fournit de la 3,4-benzocoumarine comme produit organique majeur.

Solubilité
Insoluble dans l’eau.
