Pinar, Sanjiv PrasharAbstractThe alkenyl substituted zirconocene complexes, [Zr(η5-C5H4{CMeRCH2CH2CH = CMe2})2Cl2] (R = Me (1), Ph (2) were prepared from the reaction of the lithium derivative Li(C5H4{CMeRCH2CH2CH = CMe2} (R = Me, Ph) with zirconium tetrachloride. The bulky alkyl substituted cyclopentadienyl ligand precursor was prepared as its fulvene derivative (C5H4) = CMeCH2CHMe2 (3) via the reaction of cyclopenta...

Solvent-free synthesis, characterization, biological activity of schiff bases and their metal (II) complexes derived from ferrocenyl chalcone
Publication date: Available online 14 August 2019Source: Journal of Organometallic ChemistryAuthor(s): Yuting Liu, Lisha Yang, Dawei Yin, Yang Dang, Lan Yang, Qian Zou, Jie Li, Jiaxi SunAbstractA novel efficient method for the synthesis of ferrocenyl chalcone Schiff bases and their metal (II) complexes has been developed. Schiff bases were synthesized with TsOH (p-toluenesulfonic acid) as catalyst and complexed with metal (II) salts (Zn (II), Pb (II), Cd (II), Ni (II)). The compounds were characterized by various spectroscopic techniques and elemental analysis. The thermal stability of the complexes was performed by thermo...

Hydrogenation of carbon dioxide to formate by α-diimine RuII, RhIII, IrIII complexes as catalyst precursors
Publication date: Available online 15 August 2019Source: Journal of Organometallic ChemistryAuthor(s): Nyasha Makuve, Gift Mehlana, Richard Tia, James Darkwa, Banothile C.E. MakhubelaAbstractThe conversion of CO2 into valuable chemicals has been of major interest because it is cheap and readily available. The concept of reducing CO2 pollution via its utilization into valuable products has inspired us to synthesise novel 4,4'-((1Z)-butane-2,3-diylidenebis(azanylylidene))dibenzoic acid (L) metal complexes {[(L)RuII] (C1), [(L)RhIII] (C2), [(L]IrIII (C3)} complexes for catalytic hydrogenation of CO2. The α-diimine metal...

Preparation of heptafluoronaphthyllithiums and -magnesiums: An unexpected difference in the reactivity of isomers C10F7H and C10F7Br towards organolithium and organomagnesium compounds
Publication date: Available online 11 August 2019Source: Journal of Organometallic ChemistryAuthor(s): M.M. Shmakov, V.V. Bardin, S.A. Prikhod'ko, N. Yu AdoninAbstractSignificant differences in the reactivity of isomeric heptafluoronaphthalenes and bromoheptafluoronaphthalenes towards organolithium and organomagnesium compounds were found. Metalation of polyfluorinated naphthalenes 2-C10F7X (X = H, Br) occurs easily under the action of bases (BuLi, t-BuLi, LDA) as well as EtMgBr (X = Br) in ether. This fact was proven by 19F NMR spectroscopy and by trapping of 2-C10F7M (M = Li, MgBr, Mg(2-C10F7)) with electroph...

Synthesis, structure and bonding modes of pyrazine based ligands of Cp*Rh and Cp*Ir complexes: The study of in-vitro cytotoxicity against human cell lines
Publication date: Available online 8 August 2019Source: Journal of Organometallic ChemistryAuthor(s): Agreeda Lapasam, Emma Pinder, Roger M. Phillips, Werner Kaminsky, Mohan Rao KolliparaAbstractThe reaction of multidentate pyrazine based ligands was explored towards Cp*rhodium and Cp*iridium precursors. Mononuclear and dinuclear complexes formed by the ratio-based reaction between ligand and metal precursor. The representative complexes have been determined by single crystal X-ray diffraction studies. Cytotoxicity study of the ligands and their complexes are evaluated against human colorectal cancer cell lines HT-29, HCT-...

Palladium nanoparticles decorated on a novel polyazomethine as a highly productive and recyclable catalyst for Suzuki coupling reactions and 4-nitrophenol reduction
This report displays the procedure in preparation of fast, highly productive, reusable, and easily retrievable Pd nanoparticles (NPs) as a heterogeneous catalyst (Pd NPs@P(3-MPAP)) immobilized on a novel polyazomethine with phenol group, Poly(3-methyl-4-((pyridin-2-ylmethylene)amino)phenol) (P(3-MPAP)), and the investigation of its catalytic efficiency in fabrication of several biaryl compounds by Suzuki coupling reactions and reduction of 4-nitrophenol to 4-aminophenol. The structures of the synthesized monomer, polymer support material and nanocatalyst were identified by UV–Vis, FT-IR, 1H NMR, TGA, XRD, SEM and EDS...

Efficient transfer of dithiolene ligands from nickel to cyclopentadienyl ruthenium complexes
Publication date: Available online 6 August 2019Source: Journal of Organometallic ChemistryAuthor(s): Harry Adams, Deena M. Alasali, Michael J. Morris, Sarah A. Morris, Craig C. Robertson, Voirrey L. RobinsonAbstractThe reaction of [CpRu(PPh3)2Cl] with [Ni(S2C2Ph2)2] in refluxing toluene produces the purple salt [CpRu(S2C2Ph2) (PPh3)][Cl], containing a rare example of a cationic dithiolene complex, in excellent yield. Chemical or electrochemical reduction of [CpRu(S2C2Ph2) (PPh3)][Cl] causes a colour change to blue and formation of the corresponding neutral species [CpRu(S2C2Ph2) (PPh3)]. In contrast the reaction of [CpRu(...
