Abstract
Procedure for the preparation of sulfonylureas of the formula **(See formula)** where X means hydrogen, chlorine, bromine, methoxy or methyl, Y means -CH (CH3) -CH2-, -CH2-CH (CH3) - or, preferably, -CH2-CH2-, R means, a) alcohol with 3 to 6 carbon atoms, b) cycloalkyl with 5 to 8 carbon atoms, which may be optionally substituted by 1 or 2 alcohol groups with a total of 3 carbon atoms or chlorine, c) cycloalkenyl with 5 to 8 carbon atoms which may optionally be replaced by a total of 3 carbon atoms, d) bicycloalkoxy or bicycloalkenyl with 7 to 8 carbon atoms, e) nortricicycl, f) spiro [2,4] -heptyl, and z means hydrogen or a hydrocarbon radical with 1 or 2 carbon atoms that form with Y a 5- or 6-membered ring and its salts, characterized in that a) benzenesulfonyl-isocyanates, benzenesulfonyl-carbamic acid esters, benzenesulfonyl-thiolcarbamic acid esters, benzenesulfonylureas are reacted, - semicarbazides or -semicarbazones substituted in position 4 with the group **(See formula)** or in position 3 with group Z with an amine R-NH2 or its salts, or sulfonamides of the formula are reacted **(See formula)** or its salts, with isocyanates, esters of carbamic acid, esters of thiolcarbamic acid, halides of carbamic acid or ureas, E-substituted; or b) suitably substituted benzenesulfonyl iso-urea-ethers, -isourea-esters, -isothiourea-ethers, benzenesulfonylparabanic acids or benzenesulfonyl-haloformic acid amidines, or compounds of the formula **(See formula)** wherein U means low molecular weight O-alcohol, low molecular weight S-alcohol or halogen (preferably chlorine); or c) in suitably substituted benzenesulfonyl-thiorureas, thioamidoalcohyl-benzenesulfonylureas or thioamidoaleohyl-benzenesulphonylthioureas, the sulfur atom or the sulfur atoms of the thiourea group and/or of the thioamido group is replaced by an oxygen atom or or suitably substituted carbodiimides are subjected to addition with water, or d) suitable benzenesulfinylureas or benzenesulfenylureas are oxidized, or e) in benzenesulfonylureas of the formula **(See formula)** the radical is introduced by acylation, optionally in stages. f) suitably substituted benzenesulfonyl halides are reacted with R-substituted ureas or their alkali metal salts, or suitably substituted benzenesulfinic acid halides or, in the presence of acidic condensing agents, also suitably substituted sulfinic acids or their salts are reacted of alkali metals, with NR-N'-hydroxy-urea; and the reaction products are optionally treated with alkaline agents for the formation of salts.
