| Abstract: | 7-Pyrazol-3(5)-yl]4,5,6,7-tetrahydro-1H-indazole and 6-pyrazol-3(5)-yl]-1,4,5,6-tetrahydrocyclopentac]pyrazole, potential chelating ligands, were synthesized by
condensation of 2-acetylcyclohexanone and 2-acetylcyclopentanone difluoroboron complexes with dimethylformamide dimethyl acetal
followed by cyclization with hydrazine hydrate. |
