Syntheses of Fluorine-containing N-Sulfanilylbenzamides

Abstract

Phenyl esters of o-, m-, and p-fluorobenzoic acid and 3-methyl-4-fluorobenzoic acid were prepared and fluorine-containing N-sulfanilylbenzamides were derived from these by the fusion of a mixture of 2 moles of these phenyl esters, 2 moles of sulfanil-amide, and 1-2 moles of anhydrous potassium carbonate. All these fluorine-containing phenyl esters and N-sulfanilylbenzamide derivatives are yet unknown in literature.
