This book was released on 2014-02 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Present book provides an insight to the synthesis, characterization and structural analysis of compounds containing nitrogen and sulfur containing chelating agents. Keeping in mind the biological, medicinal, industrial and chelating importance of sulfur (alone) and nitrogen containing donor ligands, two important chelating agents, viz Potassium-2-trithiocarbonatoethyl xanthate (PTEX) and 2-amino-4-benzamido thiosemicarbazide (ABTSC) have been discussed in details w.r.t. their synthesis, characterization and metals complexes. All the possible techniques have been dealt in order to elucidate the structures of the complexes generated.

Available in PDF, EPUB and Kindle. Book excerpt: Molybdenum and Molybdenum-Containing Enzymes is a collection of papers that deals with the various concerns with molybdenum-containing enzymes. The text first covers the organometallic chemistry of molybdenum, and then proceeds to tackling molybdenum-containing enzymes, such as xanthine oxidase, aldehyde oxidase, and sulphite oxidase. The text also discusses the advancement in the understanding of molybdenum-containing enzymes. The remaining chapters deal with the genetics of molybdoenzymes and the nutritional aspects of molybdenum. The book will be of great use to students, researchers, and practitioners of biochemistry.

Abstract: Abstract of thesis entitled "SYNTHESES, STRUCTURES AND REACTIVITY OF THE GROUP 6 AND 7 METAL COMPLEXES CONTAINING CHELATING NITROGEN DONOR LIGANDS AND METAL-LIGAND MULTIPLE BONDS" submitted by Lee Fu Wa for the degree of Doctor of Philosophy at the University of Hong Kong in September, 1997. ____________________________________________________________________ [Cr(CRMe )Cl ] (CRMe =meso-2,3,7,11,12-pentamethyl-3,7,11,17- 3 2 3 2+ tetraazabicyclo[11.3.1]-heptadeca-1(17),13,15-triene), [Cr(CRMe )Cl(H O)], 3 2 2+ + [Cr(CRMe )Cl(CH CN)] and [Cr(CRMe )(N )(OH)] are prepared. Upon addition 3 3 3 3 2+ 2+ of PhI=O to solutions of [Cr(CRMe )Cl(CH CN)] and [Cr(CRMe )Cl(H O)] 3 3 3 2 respectively in CH CN, the UV-visible absorption spectra of the two mixtures show similar isosbestic spectral changes attributed to the formation of V 2+ [Cr (CRMe )Cl(O)] . Addition of PhP causes the immediate recovery of 3 3 2+ [Cr(CRMe )Cl(CH CN)] as the isosbestic changes are reversed. Irradiation of 3 3 [Cr(CRMe )(N )(OH)] in acetonitrile with UV-visible light gives an azide-free 3 3 product, the FAB-MS of which shows a molecular ion peak indicative of V + + ([Cr (CRMe )(N)]ClO ). The UV-visible spectra of [Cr(CRMe )Cl ], 3 4 3 2 2+ 2+ [Cr(CRMe )Cl(H O)] and [Cr(CRMe )Cl(CH CN)] measured in water are 3 2 3 3 3+ similar to that of [Cr(CRMe )(H O) ] . Results from the conductivity measurement 3 2 2 + 2+ show that in water, [Cr(CRMe )Cl ], [Cr(CRMe )Cl(H O)] and 3 2 3 2 2+ [Cr(CRMe )Cl(CH CN)] behave as 3:1 electrolytes. The species which exists in 3 3 3+ water is likely to be the di-aquo complex [Cr(CRMe )(H O) ] . 3 2 2 2+ 2+ [Cr(CRMe )Cl(H O)] and [Cr(CRMe )Cl(CH CN)] are both found to give a 3 2 3 3 reversible oxidation couple at +1.11 V vs. SCE in aqueous solutions at pH=1 which is assigned to Cr(III)/(IV). iii t + The bis(imido) complexes [(TACN)M(N Bu) Cl] (M=Cr, Mo; TACN=1,4,7-triazacyclononane) and their 1,4,7-trimethyl derivatives are prepared, the crystal structures of which reveal the trans influence of the imido group. These 0 +/0 d species display a quasi-reversible couple at potentials 0.86 - 1.20 V vs. Cp Fe in acetonitrile assignable to a imido ligand-centred oxidation. (Me TACN)Mo(CO), 1,4,7-Tri((S)-2-methylbutyl)-1,4,7-triazacyclononane 3 3 * * * (L ) and L Mo(CO) are synthesized. (Me TACN)Mo(CO) and L Mo(CO) show 3 3 3 3 +/0 reversible oxidation couples at -0.26 V and -0.24 V vs. Cp Fe in CH CN 2 3 I/0 respectively which are assigned to Mo . The comparable electronic effect of * Me TACN and L in this system is therefore implied. 2+ [(Me TACN) Mn (μ-O)(μ-OCOCH ) ] is prepared and found to mediate 3 2 2 3 2 aziridination of styrene, methylstyrene, cis- and trans-stilbene, 1,1-diphenylethene and norbornene by PhI=NTs in CH Cl at 25 C. The nitrene transfer to cis- and 2 2 trans-stilbene is found to be stereoselective to exclusively give the trans-aziridine product. + + [(Me TACN)(CO) M CPh] (M=Mo, W) and [(TACN)(CO) Mo CPh] 3 2 2 are prepared. [(Me TACN)(CO) M CPh] (M=Mo, W) exhibit a reversible 3 2 +/0 reduction couple at -2.15 V vs Fe Cp and an irreversible wave at 0.77 V vs +/0 Fe Cp, which are ascribed to a reduction centred at the phenyl ring and oxidation of the terminal CO respectively.
