Curcumin complex compound, MLn (L = curcumin; M = Na+, Mg2+, Cu2+) has been synthesized from the reaction between curcumin and metal precursors (NaCl, MgSO4.7H2O, CuCl2.2H2O) in ethanol under reflux conditions. Synthesis takes place through the reaction between the metal ions Na+, Mg2+, or Cu2+ as the central atom and curcumin as the ligand. Curcumin has been consumed after the reaction lasts for four hours, shown by thin-layer chromatography in which a new spot appears at higher Rf as the spot of curcumin disappears in the reaction mixture.

Complexes of transition metals with chiral ligands are considered as catalysts. Among metal-containing organic complexes with semiconducting properties, compounds of the porphin series occupy a special place in electrocatalytic studies. The properties of the porphyrin macrocycle, their role in catalysis, and the influence of the nature of the metal on the catalytic properties of the complex are considered.

Abstract:
AbstractComplex hydrides are mixed ionic–covalent compounds that can serve as reversible H2 storage media only when they are catalyzed by a transition metal such as Ti. As the prime example, the phenomenology of Ti-catalyzed sodium alanate (NaAlH4) is reviewed from a historical perspective. Dehydriding yields a theoretical 5.6 wt% H2 during two-step decomposition, NaAlH4 → Na3AlH6 → NaH + Al, although 100% recovery of that H2 is not currently possible. H2 can be discharged and recharged at practical rates at 125°C. More work is needed on the alanates, in particular, as well as the identificati

N-(2-hydroxybenzal (naphtal)-dodecylamines – Shiff bases and some khelate complexes of Cu (II), Co (II) and Ni (II) transition metals with their participation were synthesized. The effects of obtained metal complexes of Bis-[N-(2-oxisalycilal (naphtal) octadecyliminates] on the performance of synthetic oils were studied as well. It is justified that obtained compounds exhibit enhanced inhibiting activity, are superior in the efficiency to the well-known inhibitor phenyl- α-naphthylamine, and comparable to tricresyl phosphate in anti-wear properties.
