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 high resolution study of the 4Â¹â bands of Â¹Â³CHâ O and CHâ Â¹â ¸O
(Brock University, 1977-07-09)
NMR studies of the exchange reactions of CH3CN.BX3 with excess CH3CN /|nJoseph Fogelman. -- 260 St. Catharines, Ont. : [s. n.],
(Brock University, 1970-07-09)
Exchange reactions between molecular complexes and excess acid or base are well known and have been extensively surveyed in the literature(l). Since the exchange mechanism will, in some way involve the breaking of the ...
Effects of sample solvent composition and injection volume on chromatographic peak profiles of methyl w- benzimidazolecarbamate and 3-butyl1-2,4-dioxo[1,2-a]-s- triazinobenzimidazole in RP-HPLC
(Brock University, 1987-07-09)
The effects of sample solvent composition and the injection volume, on the chromatographic peak profiles of two carbamate derivatives, methyl 2-benzimidazolecarbamate (MBC) and 3-butyl-2,4-dioxo[1,2-a]-s-triazinobenzimidazole ...
Molecular mechanics calculations on some phosphine oxide metal complexes in aqueous and organic solvents
(Brock University, 1991-07-09)
Molecular mechanics calculations were done on tetrahedral phosphine oxide zinc complexes in simulated water, benzene and hexane phases using the DREIDING II force field in the BIOGRAF molecular modeling program. The SUN ...
Biosynthesis of benzyliasoquinoline alkaloids
(Brock University, 1978-07-09)
This research was carried out to obtain a convenient route for the synthesis of [7_ 14C]-p-hydroxy benzaldehyde. Section 1 of the thesis includes a route involving intermediates with protecting groups like benzyl and ...
Asymmetric cyclopropanation via catalysts incorporating the 1,4-diol ligands and the newly designed dioxaborolane /
(Brock University, 2000-07-14)
The development of new methodology for the asymmetric synthesis of chiral organic compounds is a major focus in modem organic chemistry. The use of chiral catalysts is replacing chiral auxiliaries as a new tool for synthetic ...
Palladium and platinum complexes of vitamin Bâ
(Brock University, 1982-07-09)
Palladium and platinum complexes of pyridoxamine, pyridoxine and pyridoxal have been prepared. The structures of the complexes PtCI2PM.H20, trans-PdC12 (PN)2 and [PLH+ ]2[PtC16] 2- ,H20 have been determined by use of ...
Investigations into the determination of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) by capillary gas chromatography
(Brock University, 1989-11-04)
Factors involved in the determination of PAHs (16 priority PAHs as an example) and PCBs (10 PCB congeners, representing 10 isomeric groups) by capillary gas chromatography coupled with mass spectrometry (GC/MS, for PAHs) ...
The 21-dehydroxglation of corticosteroids of Eubacterium lentum and the dehalogenation of 4-chlorobenzoic acid by 4-chlorobenzoate dehalogenase
(Brock University, 1988-11-04)
Two enzyme mechanisms were investigated: the 21-dehydroxylation of corticosteroids by Eubacterium lentum and the dehalogenation of 4-chlorobenzoic acid by Pseudomonas sp. CBS 3. , Chemical and enzymic methods of ...
