Abstract

Abstract Amphiphilic pyridinium ketoximes 4-[1-(hydroxyimino) alkyl]-1-methylpyridinium bromides (1) and 1-alkyl-4-[1-(hydroxyimino) ethyl] pyridinium bromides (2) are isomeric cationic surfactants bearing the nucleophilic hydroxyimino group. They differ in the position of the nucleophilic function relative to polar head group and hydrophobic alkyl chain. The 4- nitrophenyl diphenyl phosphate (PNPDPP) cleavage by the oximate anions generated ...
