A new relation of .... modification of enzyme lysozyme
The characterisation of a new reaction of o-benzoquinone at the indole moiety of tryptophan and its application in the chemical modification of the enzyme lysozyme constitutes the present thesis. o-Benzoquinone is a highly ... -
Electronic structures
The studies pertain mainly to the correlation of electronic structure and physicochemical as well as biological properties of five different sets of biologically important heteroaromatic N?oxides, employing molecular orbital ... -
Magnetic and spectroscopic investigations of iron and other ..... Ligands
The complexes of a new ligand, 2-thioacetamido thiazole (TATZ) with halide and nitrate salts of Fe(II), Ni(II), Cu(I,II), Zn(II), Cd(II) and Hg(II) have been synthesized. The compounds have the general formula, M(TATZ)?·nH?O ... -
Physico-chemical studies on the dilute solution propertie of random copolymers ofacrylonitirle.
The large values of ‘a’, the M.H. exponent, in good solvents for both St–M and MMA–AN suggest that these molecules are highly extended in solution. Application of the different theories to calculate the unperturbed dimensions ... -
Studies in ring-chair ..... group effects
The thesis entitled "Studies in Ring-Chain Tautomerism" consists of four chapters and an appendix. A study of the kinetics of alkaline hydrolysis of methyl 3-benzoylpropionate, methyl 4-benzoylbutyrate and methyl ... -
Studies on molecular complexes of macrocyclic polyethers
The investigations report the ability of several donor macrocyclic polyethers, 15?Crown?5, 18?Crown?6, benzo?15?Crown?5, dibenzo?18?Crown?6, dicyclohexyl?18?Crown?6 and dibenzo?24? Crown?8, to form molecular complexes with ... -
Studies on perovskite type rare earth transition metal oxides as oxidation catalysts
The introductory chapter begins with a classification of the thermal decomposition of solids, followed by a brief account of the decomposition of simple and complex oxalates as well as complex nitrites. The salient features ... -
Syntheic studies in carolenoids
The thesis entitled “Synthetic Studies in Carotenoids” describes a novel route to the synthesis of vitamin A derivatives. It is divided into two chapters. The second chapter is further divided into three sections. Chapter ... -
Synthetic investigation in steroids
The thesis entitled “Synthetic Investigations in Steroids” consists of four chapters. Chapter I is a brief review on the total synthesis of aromatic steroids. The problems associated with the development of the total ... -
The crystal and molecular structures of some highly strained and moderately ... Systems
The thesis entitled “The Crystal and Molecular Structures of Some Highly Strained and Moderately Strained Organic Ring Systems” consists of two parts: Part One deals with the highly strained systems, and Part Two with the ... -
The Reactions of Coordinated ligands - A STU D Y O F THE REACTIVITY OF CO O R D IN ATED β-Diketones, β-Ketoimines, and Thio-β-Diketones
Reactions of some Schiff-base complexes of diacetoxy boron with phenylisocyanate and nitrosating reagents have been investigated. Phenylisocyanation produces phenylamido-substituted derivatives by electrophilic attack by ... -
Triphenylphosphazenyl-cyclotriphosphazenes and bicycle phosphazenes
The work presented in this thesis consists of two parts. The first part deals with the preparation of (triphenylphosphazenyl)pentachlorocyclotriphosphazene, N?P?Cl?(NPPh?) and its reactions with primary and secondary amines. ... -
X-ray crystallographic...... acetate adducts
Distances seem to be evident from the plot. With the results of the magnetic work, the above conclusion can now be examined. The parameter most appropriate for comparison is the magnitude of 2J. If the interaction is direct ... -
X-ray spectroscopic and magnetic....systems
The thesis is primarily based on detailed studies of transition metal oxide systems employing X?ray absorption spectroscopy, X?ray photoelectron spectroscopy and magnetic susceptibility measurements. Chapter I deals with ... -
X-ray structure analysis of some molecules of biological interest
The thesis entitled “X?ray Structure Analysis of Some Molecules of Biological Interest” consists of two parts. Part I (Chapters 1, 2, and 3) deals with studies on the geometry of an amide group under different chemical ...
