Thermal behavior including the cold crystallization of a Schiff base complex bearing two methyl groups was investigated. Additionally, effect alkoxy chain length studied.

Schiff base denotes a reaction product of a primary amine and a carbonyl compound. Schiff bases possess a wide variety of biological activity specially antibacterial and antifungal properties. Metal complexes of Schiff base have been studied for their biological activities. This review articles provide a summary of medicinal chemistry features of Schiff base and various reports published on bio...

Brightly NIR emissive ytterbium Schiff base complex was predicted by NMR spectroscopy and used for bioimaging. Its structure in solution determined spectroscopy.

A metal template approach affords in high yield a tetra-Zn(salphen) macrocycle (3) which shows strong and cooperative self-assembly mediated by the formation of Zn(salphen) dimer units held together via μ(2)-phenoxo interactions. A cooperative binding mode for the tetranuclear Zn(4) macrocycle 3 is supported by comparison of UV-vis and fluorescence titration data recorded for 3 when compared wi...

Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.

Schiff base ligand (E)-4-[(hydroxyl phenylimino)methyl]benzene-1, 2-diol (H3L) was prepared from the condensation reaction of Protochatechu aldehyde (3, 4-dihydroxybenzaldhyde) with 2-amino phenol. From the direct reaction of the ligand (H3L) with Co(II), Ni(II) and Cu(II) chlorides and Fe(III) and Zn(II) nitrates in 2M:1L molar ratio, the five new neutral complexes were prepared. The character...

Expansion of a Schiff-base polypyrrolic macrocycle allows the formation of a binuclear uranyl complex with co-linear uranyl ions and a very short oxo-oxo distance.
