METHOD OF SYNTHESIS OF AMINOPHENYLPERFLUOROALKYLSULFIDES Russian patent published in 1995 - IPC

Abstract RU 2030397 C1

FIELD: chemical technology. SUBSTANCE: synthesis is carried out by treatment of corresponding dinitrodiphenyldisulfides with alkaline or alkaline-earth metal in liquid ammonia and the following UV-irradiation of solution formed together with perfluoroalkyl iodide added to it. Under these conditions the yield of the end product is increased from 50-60 to 75-85%. Stages of isolation and purification of hazard aminothiophenols were excluded. EFFECT: increased yield of products, development of universal and safety method of synthesis. 2 tbl
