Description
Ethyl 3-methylpyrazole-5-carboxylate can be prepared by reacting ethyl acetylpyruvate and hydrazine.Ethyl 3-methylpyrazole-5-carboxylate may be used to synthesize the following ligands:potassium salt of new dihydrobis(3-carboxyethyl-5-methylpyrazolyl)borate (BpCOOEt,Me)[(3-carboxy-5-methyl-1H-1-pyrazolyl) (3-methyl-5-carboxy-1H-1-pyrazolyl)methane, which readily forms Zn(II) and Cd(II) complexesbis(3-carboxy-5-methyl-1H-1-pyrazolyl)methane, which readily forms Zn(II) and Cd(II) complexes
