2017年6月6日 · A novel dioxime derivative (2E,2′E,3E,3′E)-3,3′-(pyrimidine-4,5-diylbis(azanylylidene))bis(butan-2-one)dioxime was synthesized with a yield of 65%. IR, elemental analysis, mass spectroscopy and 1 H-NMR were used to characterize the structure of the synthesized compound.

2022年11月2日 · New dioxime derivatives of vitamin B6, compounds 1–7, were prepared in two steps, but the synthesis was attempted in two ways. First, a pyridoxal monooxime was quaternized with 2-bromoacetophenones, and then an attempt was made to convert the carbonyl group between the two aromatic rings into an oxime group.

2023年9月1日 · The copper(II) complex was prepared by reaction of the ligand with copper(II) perchlorate hexahydrate in methanol under constant stirring for 1 h at room temperature. The newly synthesized dioxime ligand and its Cu(II) complex were characterized by several analytical and spectroscopic methods.
