| titleOfInvention | N-Substd. sulphamoyl halides prepn. - by reacting alcohols with halosulphonyl isocyanates |
| abstract | N-Substd. sulphamoylhalide of the formula: R1-NH-SO2-X (I)(where R1 is an aliphatic, cycloaliphatic or araliphatic residue and X is halogen), e.g., tert. amylaminosulphonyl chloride, are prepd. by reacting alcohols of the formula: R1OH (II), with halosulphonylisocyanates of the formula: X-SO2-N=C=O (III), in the presence of aliphatic or cycloaliphatic hydrocarbons, halogenated hydrocarbons, ethers and/or nitriles. Cpds. (I) in which R1 is a gp. -CR2R3R4 (where R2, R3 and R4 are 1-10C alkyl, cyclopropyl, 1-4C chloroalkyl, 2-5C alkoxyalkyl, 7-12C aryloxyalkyl, 2-5C alkylthioalkyl or 7-12C arylthioalkyl and R2 can also be 6-10C aryl, 7-12C aralkyl, 2-5C alkenyl,alkynyl or alkylcarbonyl or 3-6C alkanoyl, or R2 and R3 are linked so as to form a 3- to 6-membered ring, and where R3 can also be H when R2 is aryl or aralkyl or R3 and/or R4 can be H when R2 is alkenyl or alkynyl), are new and claimed. (I) are inters. for plant protection agents, dyes and pharmaceuticals. Thus, reaction with anthranilic acid and cyclisation gives 2,1,3-benzothiadiazin-4-one 2,2-dioxide useful as plant protection agents and pharmaceuticals (DT 1542836, DT 2349114). (I) may also be converted into fungicides (DT 1953356) and herbicides (DT 2201432), and may be hydrolysed to halo-amines useful as inters. for anticancer agents. (I) may also be converted into cyclostatic N-halo- and N,N-bis(beta-haloalkyl)-sulphamidhydrazones. In addition, (I) themselves have herbicidal activity. |
