Abstract
AbstractEleven new heterocyclic mono‐and diquaternary salts have been prepared by reaction of 1,2‐bisazolyl‐ and 1,2‐bisbenzazolyl‐ethanes with methyl sulfate or methyl fluorosulfonate. Their structure has been established by means of 1H and 13C NMR spectroscopy. Homonuclear COSY and NOESY experiments and 2D‐heteronuclear correlations have been performed when necessary to assign all NMR signals.
