Using known procedures, alkylethers of pyridine-aldoxime not described as yet were prepared and transformed into pyridinium salts. The application of a solution of a,a'-di-iodo-dimethyl-ether proved especially useful in the synthesis of bisquarternary salts with formaldehyde-acetal bridge. All the new substances are ineffective in a paraoxon poisoning. On the other hand, some salts show protective action in soman intoxication.
