Abstract
Résumé/Abstract The action of sodium methanethiolate (in boiling DMF) towards haloazines (ie chloro-or bromo-pyridines and quinolines)(1)(with halogen substituent in non-aza- activated position) causes sequentially halogen ipso-substitution to methylthioazines (2) and then S-demethylation to azinethiolates (3A), which were: i) subjected to S-methylation, ii) oxidized to diazinyl disulfides (4) and iii) oxidatively chlorinated to azinesulfonyl chlorides ...
