Kinetic studies of the effect of organic sulphides on the oxidation of other sulphides /
(Brock University, 1984-06-04)
The rates of oxidation of three Organic sulphides viz. methyl phenyl
sulphide, (P), p -me thoxyphenyl methyl sulphide (M) and methyl p-nitrophenyl
sulphide (N). have been obtained in ethanol using MoO-(acac)- as
catalyst ...
Reactions of polyhalogenated aromatic compounds and related ethers with metal/ammonia solutions
(Brock University, 1982-07-09)
This work contains the results of a series of reduction studies
on polyhalogenated aromatic compounds and related ethers using alkali
metals in liquid ammonia.
In general, polychlorobenzenes were reduced to t he parent ...
A dimensional analysis of the benzylic hydroxylase active site in mortierella isabellina
(Brock University, 1994-07-09)
The spatial limits of the active site in the benzylic hydroxylase
enzyme of the fungus Mortierella isabellina were investigated. Several
molecular probes were used in incubation experiments to determine the
acceptability ...
Quantum Monte Carlo : some theoretical and numerical studies
(Brock University, 1983-07-09)
In Part I, theoretical derivations for Variational Monte Carlo
calculations are compared with results from a numerical calculation of
He; both indicate that minimization of the ratio estimate of Evar , denoted
EMC
' ...
Enantiodivergent chemoenzymatic synthesis of Balanol and approaches to the synthesis of (+)-Codine
(Brock University, 2010-10-25)
The present thesis reviews the development of a formal enantiodivergent
synthesis of the (+)- and (-)-isomers of balanol. This approach commences from a
cis-dihydrodiol derived from the enzymatic ...
Fluorescence spectra and ab initio theoretical studies of HCOOH /
(Brock University, 1989-06-04)
A fluorescence excitation spectrum of formic acid monomer
(HCOOH) , has been recorded in the 278-246 nm region and has
been attributed to an n >7r* electron promotion in the anti
conformer. The S^< S^ electronic origins ...
Arsenic speciation by ion-exchange chromatography with on- line determination by hydride generation: electronic modification of the D.C. plasma by photon counting
(Brock University, 1994-07-09)
A method using L-cysteine for the determination of arsenous acid (As(III)), arsenic
acid (As(V)), monomethylarsonic acid (MMAA), and dimethylarsinic acid (DMAA) by
hydride generation was demonstrated. The instrument used ...
Phospha-adamantanes as ligands for palladium-catalyzed cross-coupling reactions
(Brock University, 2003-07-09)
New and robust methodologies have been designed for palladium-catalyzed crosscoupling
reactions involving·a novel·class oftertiary phosphine ligand incorporating a
phospha-adamantane framework. It has been realized that ...
Synthesis of Chiral Benzimidazolylidenes from 1,10-Phenathrolines and 1,10-Phenathroline-2,9-dione /
(Brock University, 2007-06-29)
A^-heterocyclic carbenes (NHCs) have become the focus of much interest as ancillary
ligands for transition metal catalysts in recent years. Their structural variability and strong
cy-donation properties have led to the ...
Design and synthesis of new monoterpenoid derived ligands for asymmetric catalysis /
(Brock University, 1999-05-21)
The work to be presented herein illustrates several important facts. First, the
synthesis of BIBOL (19), a 1,4-diol derived from the monoterpene camphor has allowed
us to demonstrate that oxidative dimerizations of ...
