<p>N-disubstd. sulphonamides of the formula (I) are new. In (I), R=opt. substd. 6-12C aryl or 7-14C aralkyl, opt. halo-substd. 1-10 alkyl, 3-10C cycloalkyl, 2-6C alkenyl or 2-6C alkynyl, lower alkoxyalkyl, lower alkoxycarbonylalkyl, lower alkylthioalkyl, lower alkylsulphinylalkyl or lower alkylsulphonylalkyl; R1 and R2 each independently = H, 1-6C alkyl, aryl or thienyl, or together they may be 2-9C alkylene; R3=1-3C alkyl substd. by 3 to 6 halogen atoms or trihalovinyl. There may be 1-3 substituents on an aryl gp. R or in R, selected from 1-6C alkyl, 1-6C alkoxy, 1-6C alkylthio, 1-6C alkylsulphinyl, 1-6C alkylsulphonyl, halogen, trihalomethyl, NO2, CN and carboxyl. There may be up to 3 halo substits. on other R values. Sixteen cpds. are claimed including N-(1,1,2,2-tetrachloroethyl thio)-1-cyano-1-(methyl sulphona)-cyclopentane; N-(1,1,2,2-tetrachloroethyl thio)-2-methyl-2-(2'-methoxy ethylsulphnamido) -propionitrile; N-(1,1,2,2-tetrachloroethyl thio)-N-(2-cyano-2-propyl) -2-methylsulphonyl ethylsulphonamide; N-cyanomethyl -N-(1,1,2,2-tetrachloroethyl thio)-phenyl sulphonamide; N-(1,1,2,2-tetrachloroethyl thio)-2-(methylsulphonamido) propionitrile.</p> |
