Two p-substituted carboxylic acids (1a and 1b) have been utilized to synthesize ethyl esters (2a and 2b), carbohydrazides (3a and 3b), 5-substituted-1,3,4-oxadiazol-2-thiols (4a and 4b), heterocyclic ethyl esters (5a and 5b) and finally acetohydrazides (6a and 6b).
Thio- carbohydrazide H2NNHC(S)NHNH2 (abbreviated here as tch), the next higher homologue of thiosemi- carbazide, typically acts as a neutral bidentate ligand coordinating to a metal through the sulfur atom and one of the terminal nitrogen atoms, forming five- membered chelate rings [11].
