Summary: | 1,134,384. Quaternary ammonium salts of sulphonamides. FARBENFABRIKEN BAYER A.G. 21 June, 1967 [11 July, 1966], No. 28635/67. Heading C2C. [Also in Division C3] Compounds of the formula where the various R radicals may be the same or different and are monovalent alphatic, aromatic, cycloaliphatic or araliphatic radicals, are prepared by reacting an appropriate quaternary ammonium halide with an alkali metal (e.g. sodium) derivative of an appropriate sulphonamide in an anhydrous solvent, e.g. ethanol. Specified compounds are the tetra methyl ammonium salts of N-methylmethane- and N - methylbenzene - sulphonamide, the tetramethyl - and tetraethyl - ammonium salts of N-methyl cyclohexane-sulphonamide, and the phenyl benzyl dimethyl ammonium salts of N-methylbenzene-, N-methylcyclohexane- and N-ethyl cyclohexane-sulphonamido. |
