Mn‐[4‐Chlorophenyl‐Salicylaldimine‐Methylpyranopyrazole]Cl2 as a Novel Nanostructured Schiff Base Complex and Catalyst

Mn-[4-chlorophenyl-salicylaldimine-methylpyranopyrazole]Cl2 ([Mn-4CSMP]Cl2) as nano-Schiff base complex was prepared and fully characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermal gravimetric analysis, derivative thermogravimetry, scanning electron microscopy, energy-dispersive X-ray analysis, and UV–vis spectroscopy. The reactivity of nano-[Mn-4CSMP]Cl2 as a catalyst was tested on the tandem cyclocondensation–Knoevenagel condensation–Michael reaction between phenylhydrazine and ethyl acetoacetate with various aromatic aldehydes to give 4,4′-(arylmethylene)-bis-(3-methyl-1-phenyl-1H -pyrazol-5-ol)s derivatives.
