biodegration of monoterpenes by pseudomonas incognita
Terpenoids are ubiquitous in nature. Some soil microorganisms, especially species belonging to Pseudomonas, have the ability to utilize terpenes as the sole source of carbon and energy. This process of mineralization helps ... -
Investigation on intramolecular oxidation of oxydiphenols to spirodienones
The thesis entitled “Investigations on Intramolecular Oxidative Coupling: Oxidation of Oxydiphenols to Spirodienones and Their Photoisomerizations and Novel Reactions of 1?Bromomethyl?2?naphthol?tetrahydropyranyl Ether” ... -
Kinetic and synthetic investigation of the reactions os halogeno and arlyosycyclophosphazenes
The reaction of hexafluorocyclotriphosphazene, N?P?F? (14), with sodium phenoxide in THF yields phenoxy?substituted fluorocyclotriphosphazenes of all degrees of substitution. The results obtained in this investigation ... -
Norrish type 1 Cleavage reactions of cyclobutanethiones and media
The thesis entitled "Norrish Type I ?-Cleavage Reactions of Cyclobutanethiones and Photochemical Studies in Micellar Media" has been divided into two parts. Part I deals with the strain-assisted ?-cleavage reactions of ... -
Structural and thermal studies on hydrazinum (1+) metal sulfate and oxalate complexes
Coordination compounds of hydrazine are of particular interest because of the variety of ways in which hydrazine can be coordinated to the metal ion. Apart from its ability to function as a monodentate ligand, another ... -
Study of vibrational spectra and donacity of some sulphur-nitrogen compounds containing; thiocarbonyl grouping
The infrared and Raman spectra of 1,3,4,6-tetrahydropyrimidine-2-thione (tpt) and -2-one (tpo) are studied. The infrared spectra of oriented polycrystalline samples of tpt and imidazolidine-2-thione (ethylenethiourea, etu) ... -
synthetic and structural studies in terpenoids
The thesis entitled “Synthetic and Structural Studies in Terpenoids” consists of three chapters. Chapter I deals with synthetic studies on diterpenoids calyenone (1), calyone (2), and precalyone (3) isolated from Roylea ... -
synthetic studies in emmotins and related compounds
The thesis entitled "SYNTHETIC STUDIES IN EMMOTINS AND RELATED COMPOUNDS" consists of seven chapters. Chapter 1, the total synthesis of emmotin-G (12), a sesquiterpene occurring in Emmotum nitens, is described. The ... -
Synthetic studies in steroids
The thesis entitled “Synthetic Studies in Steroids” consists of three chapters. The first chapter contains a brief review of the total synthesis of aromatic steroids, highlighting some of the theoretical and experimental ...
