Six synthesized sulfonamides

Obtained by the interaction of 2-amino-3,3-dichloroacrylonitrile and chlorosulphonyl isocyanate (Z)-(5-(dichloromethylene)-2-oxoimidazolidin-4-ylidene)sulfamoyl chloride reacts easily with excess of the aliphatic amine to form new (Z)-N-(5-(dichloromethylene)-2-oxoimidazolidin-4-ylidene)-N'-substituted sulfonamides.
