Synthesis, spectral characterization and electrochemical properties of 1H-3-(o-, m- and p-ferrocenylphenyl)-1-phenylpyrazole-4-carboxaldehydes

New ferrocene derivatives - 3-(o-, m- and p-ferrocenylphenyl)-1-phenylpyrazole-4-carboxaldehydes were synthesized and characterized by spectroscopic data and cyclovoltametric parameters. The X-ray crystal structure of the ortho-derivative is also presented.
