PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
Herein we describe the synthesis of novel substituted 6a gimel (4)-thia-1,6
-diazapentalenes by a base-induced dimerisation of two isothiazolium salts.
It was possible to introduce benzo crown ether substituents for the first
time according to the well established reaction procedure for the synthesis
of the thiadiazapentalenes. The complex formation behaviour of the 6a gime
l (4)-thia-1,6-diazapentalenes towards Ag(I), Hg(II) and Na(I) in solution
was studied in terms of the influence of several substituents. The combinat
ion of 6a gimel (4)-thia-1,6-diazapentalenes with benzo crown ether substit
uents results in a simultaneous binding of one hard and one soft metal ion
by one molecule.
