Book Synthesis and Characterization of Oxomolybdenum and Oxovanadium Complexes

Download or read book Synthesis and Characterization of Oxomolybdenum and Oxovanadium Complexes written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis and characterization of two different O-N donor hydrazide ligands and their corresponding dioxomolybdenum(VI) and oxovanadium(V) complexes have been reported. The hydrazides synthesized, are characterized by IR spectroscopy and by C, H, N, analysis. The ligands were directly used for metallation with metal precursors having acetyl acetonate groups. One of the acetyl acetonate groups get separated from the metal precursor and carbonyl group of that acetyl acetonate group undergoes condensation with hydrazide forming insitu hydrazone ligand. The complexes formed are also successfully characterized by IR, UV-Vis, C, H, N analysis and cyclic voltammetry.

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mo(VI) complexes of selected ONO donor ligands may mimic the active sites of some oxotransfer molybdoenzyme and hence it is of great interest in bio-inorganic chemistry. I have been studying the chemistry molybdenum with O-N containing donor environments since one year. In this dissertation I have reported the synthesis and characterization of several O-N Schiff base hydrazone ligands and their corresponding oxomolybdenum(VI) complexes. All the synthesized ligands and corresponding Mo(VI) complexes has been characterized by several spectroscopic (IR, UV-Vis) technique and redox properties were explored by cyclic voltammetry.

Book Synthesis And Characterization Oxo mido Tris 3 5 Dimethyl Pyrazol Borate Molybdenum Complexes

Download or read book Synthesis And Characterization Oxo mido Tris 3 5 Dimethyl Pyrazol Borate Molybdenum Complexes written by Engin Şahin and published by . This book was released on 2004 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study two new reactions related to oxo-Molybdenum(V)trispyrazolyl chemistry were investigated. The reactions between [MoTp*(O)Cl2] with o-substituted anilines, H2NC6H4X-o (X= Cl, Br) in the presence of triethylamine in toluene carried out to prepare dinuclear oxo-imido Mo(V) complexes of the type [MoTp*(O)Cl](.-O)[MoTp(Cl)(.NC6H4X-o)]. Surprisingly, the previously reported compound, [MoTp*(O)Cl]2(.-O)], was obtained as the major product of both reactions. The compound [MoTp(O)Cl]2(.-O)] was characterized by 1H-NMR; IR, UV-visible spectroscopy techniques.

Book Synthesis Characterization and Catalytic Activity of Molybdenum VI Di and Monooxo Aryloxides

Download or read book Synthesis Characterization and Catalytic Activity of Molybdenum VI Di and Monooxo Aryloxides written by Mauricio Quiroz-Guzmán and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of molybdenum is immensely rich and diverse. Molybdenum is essential for life, and has many applications in industry. The first chapter offers a general perspective of the chemistry of molybdenum in high oxidation states dominated by diverse oxo species, such as the MoO22+ and MoO4+ units that are focus of my research. I describe the importance of MoO22+ complexes as models for the active sites of oxo transfer molybdoenzymes (e.g. DMSO oxidase) and for industrial heterogeneous transformation such as the SOHIO process (one of our ultimate goals). I also outline the importance of MoO4+ complexes as procatalysts for metathesis polymerization and as models of deoxygenated active sites of MoO22+ oxygen catalysts that have triggered our interest. The second chapter introduces the synthesis and full characterization of 4-, 5- and 6-coordinated MoO2(OAr)2L0-1 complexes with bulky aryloxide ligands, starting from the MoO2Cl2 or MoO2Cl2(DMF)2 precursors. Steric and electronic modifications in the aryloxide moieties were performed in order to understand their effect in the final structure and yields of the synthesized complexes. The nature and mechanism of formation of the radical species detected in their synthesis is proposed. The third chapter presents the facile synthesis of varios MoO(OAr)4-nCln complexes starting from the MoO2Cl2 precursor. Their mechanism of formation is proposed and the supporting evidence for this new reaction is provided. Steric and electronic modifications in the aryloxide moieties were used to study their structural and electronic effects in the MoO4+ complexes. The fourth chapter outlines the synthesis of Mo(VI) monooxo bisphenoxides with a characteristic cis-chloro cis-bisphoxide arrangement around the MoO4+ unit. Electronic and steric modifications in the bisphenoxide rings were done to determine their effect in the structure and reactivity of the final complexes. The fifth chapter introduces the application of the synthesized MoO(OAr)4-nCln and MoO(bisphenoxides)2Cl2 complexes as procatalysts for olefin metathesis polymerization of norbornene. The correlation between structure and reactivity of the procatalyst is discussed.
