Synthesis and Characterisation of 4-Acyl-3-methyl-2-pyrazolin-5-one Complexes of Aluminium

摘要

Reactions of 4-acyl-3-methyl-1-phenyl-2-pyrazolin-5-ones (lig.) (acyl = acetyl, propionyl, benzoyl and Cl-benzoyl) were carried out with aluminium isopropoxide and aluminium trichloride (acyl = benzoyl) in different stoichiometric ratios in non-aqueous solvents yielding corresponding derivatives having formulae Al(OPri)3-n(lig.)nand AlCl3-n(lig.)n, respectively.
