The 1,3,4-thiadiazole annelation based on the reaction of acyl chlorides with methyl 2-methyldithiocarbazate followed by cyclization with perchloric acid and further reaction with primary amines, allows the preparation of a novel kind of ligands bearing two or three 1,3,4-thiadiazole rings connected either by an aliphatic, aromatic or heteroaromatic bridge.
