Electro-catalytic reactions
… the utility and advantages of redox catalytic reactions and small scale synthetic applications. In particular electro-catalytic reactions are investigated along with electrogenerated chemiluminescence (ECL). ECL is used both as a probe for investigating the redox reactions and as an analytical …

Metal-catalyzed reactions.
… of olefins and in nucleophilecatalyzed reactions. Indenylrhodium(olefin)2 (and other Cp-derived rhodium complexes) were utilized in the directed hydroboration reactions. Both iron and ruthenium complexes with n-bound heterocyclic ligands were utilized in the study of nucleophilic …

Reactions of cyclomanganated compounds
This thesis describes novel reactions of cyclomanganated compounds of the general form shown below. The ligand is bonded by a metal-carbon σ-bond, with X acting as a donor atom to form the chelate ring. The organic ligands were derived from aryl and heteroaryl ketones, chalcones, dienones and …

Photonuclear reactions near threshold
A number of photonuclear reactions have been studied using the University of Saskatchewan betatron as a source of high energy x-rays. The gamma neutron threholds and reaction cross sections have 100% abundance in one stable isotope. These reactions have been studied by observing the emitted …

Organocatalytic conjugate addition reactions
We have found a route that uses direct Michael reaction to synthesize various butenolide structures. Its feasibility is displayed from its tolerance to a wide range of different substituted alpha, beta-unsaturated lactones and maleimides. Chiral sulphonamide catalyst proved to be an efficient …

Studies in photonuclear reactions
Progress in the theory of photonuclear reactions has been achieved principally through the extensive use of reaction models. These models have been the basis for obtaining theoretical estimates of the broad features of photon induced reactions. In medium- and heavy-weight nuclei, the predicted …

Catalytic Reactions of Organoboranes
Organoboranes represent a privileged class of intermediates and are integral to the syntheses of numerous medicinally relevant molecules. The synthesis of organoboranes is usually through 2 electron polar methods which often involve expensive and toxic reagents used in stoichiometric quantities. We …

Cycloaddition Reactions of (Di)tetrelenes
This thesis examines a variety of cycloaddition reactions of multiply-bonded heavy analogues of carbon. With the aid of a mechanistic probe, the mechanism of the addition of alkynes to a germene and a digermyne was examined. In both cases, the addition does not involve the itermediacy of an vinyl …
