A new preparation of dimethyl N,N'-(alkylene)bisdithiocarbamates and tetramethyl N,N'-(alkylene)bisdithiocarbonimidates from aliphatic diamines is reported.The reaction of the dimethyl bis(dithiocarbamates) with several aromatic dinucleophiles provides a new entry to dibenzothiazoles, dibenzoxazoles and dibenzimidazoles.Since the two heterocyclic units are connected in all cases by a flexible bridge, the title compounds represent new and promising tetradentate ligands towards the formation of a variety of cationic or neutral complexes with metal atoms.Key words:Bisdithiocarbamates; Bisdithiocarbonimidates; Diheterocycles; Dibenzothiazoles; Dibenzoxazoles; Dibenzimidazoles
