Synthesis and Characterization of Poly(Thiooxamide) Metal Complexes,ls in biologically important macromolecules. Synthesis of novel macromolecular complexes of Zn, coordinated via S and/or N should be beneficial for the future research in this field. Among S and N containing ligands, dithiooxamide and its N, N’- substituted products are particularly interesting, sin

Multi-Electron Transfer Process of a Vanadium Dinuclear Complex for Molecular Conversions, is usually enhanced by the deoxygenation of oxo complexes of vanadium (IV) to produce six- coordinate vanadium (IV) complexes.. Since vanadium (V) is a strong oxidant and vanadium (III) and, sometimes, vanadium (IV) can be oxidized by O. redox processes involving the V(IV)/V(III) and V(V)/V(IV) cou

Synthesis of High Molecular Weight Poly(Phenylene Sulfide) through Oxidative Polymerization with Ox raw materials. The most successful example is the oxidative polymerization of 2, 6-dimethylphenol to yield poly (2, 6-dimethyl-1,4-phenylene oxide) using a copper-amine catalyst in an oxygen atmosphere at room temperature(Eq. 1).. Our studies on the preparation of poly (p-phenylene sulfide) (PPS),

Poly(Phenylmetallosiloxane)S: Synthesis, Structure and Properties,lity and electrical conductivity. The chemistry of metallosiloxane polymers has already been studied for 25–30 years. The question about their structure was open until the beginning of 1990 when we have first obtained and structurally characterized poly (phenylmetallosiloxane)s (PPMS), containing bi
