Studies on the moulting hormones of the desert locust schistocerca gregaria
Thesis
Woodbridge, A. Studies on the moulting hormones of the desert locust schistocerca gregaria. https://keele-repository.worktribe.com/output/412857

A systematic investigation of extracts of late 5th instar nymphs of the desert locust Schistocerca gregaria has been carried out to detect and isolate moult-inducing substances. Moulting activity was detected by bioassay using the isolated abdomens o... Read More about Studies on the moulting hormones of the desert locust schistocerca gregaria.

Some studies of vibrational relaxation using a shock tube
Thesis
Gutteridge, R. Some studies of vibrational relaxation using a shock tube. https://keele-repository.worktribe.com/output/412913

The vibrational relaxation of HCl, HBr, HI or DCl has been studied either as a pure gas or in mixtures with argon, nitrogen or carbon monoxide. Infrared radiation from the second or third vibrational levels was used to follow the relaxation process.... Read More about Some studies of vibrational relaxation using a shock tube.

Studies of the reactions of 3H-pyrrolizines with acetylenes
Thesis
Johnson, D. Studies of the reactions of 3H-pyrrolizines with acetylenes. https://keele-repository.worktribe.com/output/412921

An attempt was made to synthesise azonia-azulenium salts by the 2+2 cycloaddition of acetylenes to 3H-pyrrolizine, and the subsequent ring expansion of the cyclobutene product.
In Part I the attempted syntheses of some new 3Hpyrrolizines are describ... Read More about Studies of the reactions of 3H-pyrrolizines with acetylenes.

Studies on the structure of the insect feeding inhibitor azadirachtin
Thesis
Percy, G. Studies on the structure of the insect feeding inhibitor azadirachtin. https://keele-repository.worktribe.com/output/412925

Azadirachtin C35H44O16, a locust feeding inhibitor, was first extracted from neem seeds by Butterworth in 1967. Butterworth identified two acetate esters, two carboxymethyl groups, a tiglate ester, two hydroxyl groups and a 2,3-dihydrofuran ring in t...

Researches into the function of metal halides in cationic polymerisation
Thesis
Grattan, D. W. Researches into the function of metal halides in cationic polymerisation. https://keele-repository.worktribe.com/output/412941

The work was concerned with the study of the ionisation of aluminium halides in alkyl halides, and the role of these solutions in cationic polymerisatlons. These are problems of long standing interest which became topical through the proposal of a ne... Read More about Researches into the function of metal halides in cationic polymerisation.

A study of the rearrangement products from isoxazolopyridinium salts

Brief treatment of tetrahydro-4-oxoisoxazolo [2,3-a]
pyridinium bromide and its 3-methyl derivative with boiling acetic anhydride gave 4-acetyl-5,6-dihydro-4H-furo [3,2-b] pyrid-2-one and its 3-methyl counterpart.
The structures of these rearrangem... Read More about A study of the rearrangement products from isoxazolopyridinium salts.

Synthesis and properties of thieno- and furo- tropones
Thesis
Robinson, M. J. Synthesis and properties of thieno- and furo- tropones. https://keele-repository.worktribe.com/output/412957

The synthesis of thieno[3,2-b]troponesand furo-[3,2-b]tropones by dehyrdrobromination of ?-dibromoketones using lithium carbonate in anhydrous N,N-dimethylformamide is investigated. Synthetic routes to furo[3,2-b]tropone and to three substituted thie... Read More about Synthesis and properties of thieno- and furo- tropones.

Intramolecular nitrene insertions into aromatic systems
Thesis
Carde, R. N. Intramolecular nitrene insertions into aromatic systems. https://keele-repository.worktribe.com/output/412975

A study of the intramolecular insertion reactions of aryl nitrenes is described.
In Part I the preparation and photolytic decomposition of a number of aryl azides in diethylamine is described. The usual products were 3H-azepines but in one case ring... Read More about Intramolecular nitrene insertions into aromatic systems.

The thermochemistry of some transition metal complexes
Thesis
McNaughton, J. L. The thermochemistry of some transition metal complexes. https://keele-repository.worktribe.com/output/413243

In this thesis, thermochemical data for two different groups of transition-metal complex are reported.
The first group of complexes is of the type MX2Ln, where M is a first-row transition-metal or Cd, X is a halogen and L is a heterocyclic ligand. T... Read More about The thermochemistry of some transition metal complexes.

A chemical investigation into the moulting hormones of the barnacle Balanus balanoides
Thesis
Morton Bebbington, P. A chemical investigation into the moulting hormones of the barnacle Balanus balanoides. https://keele-repository.worktribe.com/output/413251

In an attempt to detect and identify the moult-inducing substances in the barnacle, Balanus balanoides, one and a half metric tonnes of barnacle material was collected and extracted. Two known arthropod moulting hormones were detected in significant... Read More about A chemical investigation into the moulting hormones of the barnacle Balanus balanoides.
