Abstract
Abstract A number of new quaternary ammonium salts of n-substituted palmitamides have been prepared by conventional methods. These derivatives have been characterized by exhibiting antimycotic activity and three of the derivatives, 4-palmitoyl-1,1dimethylpiperazinium iodide, (2palmitoylaminoethyl)trimethylammonium iodide, and 4-palmitoyl-1methyl-1-(1,4,5,6,7,7-hexachlorobicyclo(2.2.1)-hepta-2,5-diene -2methylene)piperazinium bromide have been further characterized by exhibiting nematocidal activity.
