Zusammenfassung:Compounds of the formulae wherein R1-R5 represent alkyl or aralkyl radicals, R1 and R2 may complete an heterocyclic nucleus, R5 may be hydrogen, X is an anion, R is a bivalent organic radical and Z completes an heterocyclic nucleus are prepared by alkylating or aralkylating tertiary amine-N-oxides. Preparations 1-11 relate to compounds prepared from pyridine or triethylamine N-oxides.
