1-Thiocarbamoyl(ferrocenyl)-4,5-dihydropyrazoles

Thiosemicarbazide reacts with aryl β-ferrocenylvinyl ketones and β-arylvinyl ferrocenyl ketones in the presence of ButOK to give 1-thiocarbamoyl-5- and -3-ferrocenyl-4,5-dihydropyrazoles, respectively. The complexes of 3-ferrocenyl-5-phenyl-, 3,5-diferrocenyl-, and 3-ferrocenyl-5-p-methoxyphenyl-1-thiocarbamoyl-4,5-dihydropyrazoles with CuII are described.
