The preparation of racemic and optically active beta-amino-acids and their utilisation in peptide formation.
… chiral B-lactam during Wolff rearrangement in an inert solvent. Elsewhere in this thesis, it has been demonstrated that the formation of cyclohexylamide 89 as a side-product during peptide coupling of B-amino- pivalic acid with the acid of DCCI is due to alkaline cleavage of N-acylurea.

Nuclear Magnetic Resonance Spectroscopic Studies of the Role Steric Effects in Molecular Interactions Using Rationalised Data Processing Procedures
… aliphatic molecules (solutes) and aromatic solvent molecules. Several problems have become apparent regarding the evaluation of data determined from such studies, namely that the equilibrium quotient (K) and the full aromatic solvent induced shifts (4,) are found to depend on the …

N.M.R. Studies of the Formation of Molecular Complexes in the Liquid Phase
… polar aliphatic molecules (solutes) and aromatic solvents. The complexes are studied by the use of 1H chemical shifts and spin-lattice relaxation times. The purpose of the work is to confirm the validity of procedures which have been developed previously to obtain more meaningful parameters than …

Synthesis and characterization of ionic liquid electrolytes for use in electrical energy storage devices at elevated temperatures
… is the flammable and volatile carbonate-based solvent electrolyte. A significant barrier hindering the replacement of carbonate-based solvents is the inability to identify thermally stable solvents that display equivalent properties. Room temperature ionic liquids (RTILs) are ideal candidates …

Elucidation Of Chiral Recognition Mechanisms Of Solutes By Amylose Tris[(s)-Alpha-Methylbenzylcarbamate] Sorbent
… concentration of a competitive modifier in an inert solvent. In previous models the slope was inferred to be equal to the total number of the modifier molecules displaced from the sorbent and from the solute-modifier complex upon adsorption of a solute molecule, and were presumed to be …
