Structure and reactivity studies of simple phospholes
Newer techniques of phosphole synthesis, particularly those which lead to simple phospholes substituted with active functional groups, are briefly surveyed. A detailed account of chemical, physico-chemical, spectroscopic ...
Dielectric studies of molecular and intramolecular motions in polystryrene matrices
Dielectric absorption studies of a variety of polar solutes containing rotatable groups and of some analogous rigid molecules dispersed in atactic polystyrene have been carried out. Preparation of the solutions as solid ...
Temperature effects on the far-infrared absorption spectra of simple organic molecules
The recent development of interferometers operating in the far-infrared frequency region, coupled with the use of modern high-speed digital computers for processing the interferometric data, has made this frequency ...
Photolysis of para-substituted styrene polymers
This thesis describes the photolysis of para-substituted styrene polymers. Poly(vinylacetophenone), poly(p-bromostyrene), poly(p-chlorostyrene), poly(p-fluorostyrene), poly(p-isopropylstyrene), poly(p-methoxystyrene), ...
Some studies of dielectric relaxation
A general correlation function is firstly reviewed in line with Kubo's formulation (Chap. 1, (a)), and dielectric relaxation processes together with some fundamental properties are considered with the help of the function ...
Studies of the catalytic activities and resistance to sulphur poisoning of P-3 nickel and P-3 cobalt borides
The heterogeneous liquid-phase catalytic hydrogenation of alkenes over partially hydrogenated P-3 nickel and P-3 cobalt borides has been investigated.
Partial synthesis of chaksine
This thesis is concerned with the preliminary studies in the synthesis of a monoterpenoid alkaloid, chaksine, Ethyl 2-methylcyclohexanone-6-carboxylate (XI) was hydroxymethylated with formaldehyde to give Ethyl 2-me ...
Some ring expansions and related reactions of the phosphole system
The chemistry of simple phosphole derivatives is comprehensively reviewed to the early part of 1970. Using 1,2,5-triphenylphosphole and some of its derivatives as starting materials, several ring expansion and related ...
Synthesis of model compounds related to the tetranortriterpenes
In this thesis some preliminary studies have been described, which were aimed at the synthesis of compounds in which a 3-substituted furan is attached to a 6-lactone ring so as to yield structures of the type observed ...
