Structure and reactivity studies of simple phospholes
(1977)
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
(1977)
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
(1971)
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
(1977)
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
(1973)
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
(1976)
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
(1976)
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
(1970)
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
(1971)
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 ...
