Halogenated Heterocycles for Drug Discovery
… at a late stage. Our approach is to take highly halogenated heterocyclic systems and use them as scaffolds for the synthesis of novel compounds by the sequential replacement of halogen atoms with other functionalities. This approach has led to the generation of a number of novel highly …

Degradation Of Halogenated Aliphatic Compounds In Sequential Anaerobic
The objective of this study was to utilize an alternating anaerobic/aerobic sequence to biologically transform perchloroethylene to non-hazardous end products such as ethylene, CO2 and H2 using a single microbial consortia in a methanogenic and/or a homoacetogenic environment followed by a aerobic …

Effect of pH and Temperature on Halogenated DBPs
… residuals were exhausted. The results show that halogenated DBPs degrade through based-catalyzed dehalogenation processes. The degradation of TOC1, TOBr, and TOI increased with increasing pH values. Increasing temperatures also increased the degradation kinetics of these DBPs. Iodinated DBPs were …

A Convenient Synthesis of Pyrrolnitrin and Related Halogenated Phenylpyrroles
… pyrrolnitrin 1.2, along with several analogous halogenated phenylpyrroles. The proposed synthetic protocol involved the Suzuki-Miyaura cross-coupling of appropriately halogenated pyrrole pinacolboronate esters and aryl compounds. In the efforts towards preparing the cross-coupling partners, we …

Halogenated 1'-methyl-1,2'-bipyrroles (MBPs) in the northwestern Atlantic
Halogenated 1’-methyl-1,2’-bipyrroles (MBPs) are a distinctive class of marine organic compounds. They are naturally produced, they have a unique carbon structure, they are highly halogenated, and they bioaccumulate in upper trophic levels. MBPs share many characteristics with persistent organic …

An investigation into fungal metabolism of halogenated and related steroids
Fungal metabolism of halogenated and related steroids was investigated. The fungi Aspergillus niger ATCC 9142, Curvularia lunata NRRL 2380 and Rhizopus stolonifer ATCC6227b were studied in this regard. 2l-Fluoro-, 2l-chloro, 2l-bromo- and 2l-methyl-pregn-4-ene-3,20diones were prepared and incubated …

Gas phase vacuum-ultraviolet (vuv) spectroscopy of small halogenated polyatomic molecules
… is concerned with photoexcitation of small and halogenated molecules in the gas phase with vacuum-ultraviolet (VUV) radiation. For all the experiments described in this thesis, the source of radiation was from tuneable VUV radiation from a synchrotron source. The majority of the experiments used …

Reactions of Halogenated Ethylenes on the α-Cr₂O₃ (101̅2) Surface
The thermally induced reaction of halogenated ethylenes on the α-Cr₂O₃ (101̅2) single crystal surface results in the formation of gas phase hydrocarbons including acetylene, ethylene, butadiene, and dihydrogen, and deposition of surface chlorine adatoms. No surface carbon or combustion products are …

Separation and Characterization of Unknown Halogenated Disinfection by -Products in Drinking Water
By applying the technique of quantitative structure-activity relationships, the decomposition rate constants of six iodinated trihaloacetic acids were estimated. It is quite likely that dichloroiodoacetic acid and bromochloroiodoacetic acid may be found in some drinking waters.

The interaction of some halogenated anaesthetic agents with hepatic drug metabolizing enzymes
This thesis comprises a report of investigations into the interaction of the volatile anaesthetic agents, fluroxene, 2,2,2-trifluoroethyl ethyl ether(TFEE), methoxyflurane and enflurane, with hepatic drug metabolizing enzymes in vivo and in vitro. Each of the anaesthetic agents interacts with the …
