Some
metal complexes were synthesized from Schiff base derived from 5-chloro-2-hydroxyacethophenone
and N-aminopyrimidine-2-one. All compounds were characterized by elemental
analyses, molar conductivity and magnetic measurements, IR, UV-Vis, Mass and
NMR (for Pd (II)) spectral and analytic techniques. While Pd(II) complex
displayed square planar geometry, the others exhibited octahedral geometry. The
whole complexes showed non-electrolytic behavior. While Cu(II) and Co(II)
complexes exhibited partial antiferromagnetic properties, Pd(II) complex showed
diamagnetic property. Schiff base compound and new synthesized its some
complexes were evaluated for cyclohexane oxidation under microwave irradiation.
Both the microwave power and the novel catalysts were found to affect the
selective oxidation of cyclohexane (CyH) to cyclohexanone (Cy = O) and
cyclohexanol (Cy-OH). Cu(II) and Co(II) complexes were found to be more active
in the reaction of the oxidation of cyclohexane than in the ligand and other
complexes.

5-kloro-2-hidroksiasetofenon ve
1-Amino-5-Benzoil-4-fenil-1H-pirimidin-2-on’dan (N-aminopirimidin-2-on) türeyen Schiff bazının bazı metal
kompleksleri sentezlenmiştir. Bütün bileşikler elementel analiz, molar
iletkenlik, manyetik moment ölçümü, IR, UV-Vis, kütle ve NMR (sadece Pd(II))
gibi spektral ve analitik tekniklerle karakterize edilmiştir. Pd(II) kompleksi
kare düzlem geometriye sahipken, diğer kompleksler oktahedral yapıya sahiptir.
Kompleksler iletkenlik özelliğine sahip değildir. Cu(II) ve Co(II) kompleksleri
kısmi antiferromanyetik özellik gösterirken, Pd(II) kompleksi diyamanyetik
özelliktedir. Schiff baz bileşiği ve yeni sentezlenen kompleksleri mikrodalga
ışını altında siklohekzan oksidasyonu için incelenmiştir. Hem mikrodalga gücü
hem de yeni katalizörlerin siklohekzanın (CyH) siklohekzanon (Cy=O) ve
siklohekzanole (Cy–OH) seçici yükseltgenmesini etkilediği görülmüştür. Cu(II)
ve Co(II) komplekslerinin liganda ve diğer komplekslere oranla siklohekzanın
oksidasyonu reaksiyonunda daha aktif oldukları bulunmuştur.
