Investigations on the total synthesis of oxasteroids
The thesis is divided into three parts: Part I: Review A review of the chemistry of known oxasteroids with particular emphasis on: Total synthesis Physiological activity Part II: Introduction Outlines the objectives ... -
Synthetic investigations on Azulenes
At present a variety of methods for the synthesis of azulenes are available. These can be divided under three main heads: I. Methods involving a change in ring size II. Methods by which a 7-membered ring is built on a ... -
Synthesis of fused heterocyclics
The thesis consists of two parts. Investigations on quinolinoquinolines are embodied in the first part, and investigations on (C3)quinazolones are embodied in the second part. Preceding the two parts, there is a brief ... -
Investigations on the total synthesis of testorterone and its isomers : A thesis submitted to the I.I.Sc. for the degree of doctor of philosophy.
The thesis entitled "Investigations on the Total Synthesis of Testosterone and its Isomers" is divided into two parts. Part I consists of a comprehensive review of the earlier work done on the chemistry of testosterone and ... -
Synthetic studies in terpenes synthesis of the cis, trans-C-11 acid : The degradation product of agathic acid
The thesis entitled "Synthetic Studies in Terpenes – Synthesis of the cis/trans-C-11 Acid, the Degradation Product of Agathic Acid" is divided into two chapters. Chapter I is a comprehensive review of the chemistry of the ... -
studies in synthesis of 6-oxasteroids
Thesis Title Studies in: (I) Synthesis of 6-Oxasteroids and (II) Ultraviolet Spectra of 1,2-Dicyano Esters and Related Compounds The thesis is divided into three parts: Part I: Synthesis of 6-Oxasteroids Chapter I: A ... -
Studies on the solid state decomposition of oxalic acid and ammonium oxalate Ph.D. Thesis
This thesis embodies studies on the photolysis of oxalic acid and ammonium oxalate and the low-temperature thermal decomposition of ammonium oxalate. From a detailed review of the literature, it was evident that very few ... -
Contributions to the chemistry of disulfur monoxide
Disulfur monoxide is an unstable gaseous species. Even at comparatively lower temperatures, it undergoes decomposition into sulfur dioxide and elemental sulfur. When dissolved in chilled carbon tetrachloride, the solution ... -
Dilute solution on properties of Methyl Methacrylate-Acrylonitrile random Copolymers
The large values of a, the M.H. exponent, suggest that these molecules are highly extended in the solvents studied. Application of S.F. and other existing theories like I.P. to calculate the unperturbed dimensions lead to ... -
Dynamics in complex systems: liquid crystals, biological water, supercooled water and enzymes
The origin of the glassy orientational dynamics, both single particle and collective, of nematogens near the isotropic-nematic transition has been addressed in several publications in recent years [5-7, 12]. In these ... -
Electron spectroscopic studies of the adsorption and reactivity of oxygen on transition metal surfaces covered with alkali and alkaline earth metals
Characteristic Cl(2p) and O(1s) peaks are seen by XPS attributable to distinct adsorbed chlorine and oxygen species on potassium and barium dosed Ag surfaces: a) There is selective stabilization of molecular dioxygen species ... -
Investgations of molecular interaction by photoelectron and electron energy loss spectrospies
Electronic structures of a variety of electron donor-acceptor complexes have been studied by employing ultraviolet (HeI) photoelectron spectroscopy. The systems studied are the complexes of BH? / AlCl?, GaCl? and SO? with ... -
Studies of surfaces by electron spectroscopy
All the organic molecules containing lone-pair orbitals adsorb molecularly (associatively) on copper at low temperatures (<100 K). b) It is possible to estimate the stabilization of the lone-pair orbitals due to chemisorption ... -
Structure - reactivity correlations of photochemical & thermal reactions in the solid state
The thesis entitled "Structure-Reactivity Correlations of Photochemical and Thermal Reactions in the Solid State" has been divided into two parts. Part I deals mainly with studies on the role of steering groups such as ...
