Ferrocenyl-substituted 1,3,4-oxadiazoles, 2-ferrocenyl-1,3,4-oxadiazole (1) and 2,5-diferrocenyl-1,3,4-oxadiazole (2), have been prepared from the corresponding hydrazides, (ferrocenecarbonyl)hydrazine (3) and 1,2-bis(ferrocenecarbonyl)hydrazine (4), and characterized by conventional spectroscopic methods (IR, NMR, MS) and elemental analyses. The solid-state structures of 1, 2 and 4 have been determined by single-crystal X-ray diffraction analysis.
Electrochemical properties of compounds 1 and 2 were further studied by voltammetric techniques.
