The relative rates of hydrogen atom abstraction from a series of
13 homoaryl and heteroarylmethanes by t-butoxy radical were determined at 70°C. The attacking radical was photochemically generated
from di-t-butyl peroxide. A relatively small range of relative rates
(factor of seven) has been found among the compounds studied. The
relative...
To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems.
A quantitative analytical...
The relative rates of hydrogen atom abstraction from a series of 13 homoaryl
and heteroarylmethanes by the nucleophilic undecyl radical, thermally generated
from lauroyl peroxide, were determined at 70 °C. A reactivity range of 15 was
obtained. Substantial differences in reactivity among isomers were found. The
relative reactivities of the...
In this dissertation, I describe the experimental investigation of large superfluid helium droplets. The goal and direction of this thesis is to facilitate the use of these droplets as part of our project ss-EDI. The overall scheme of ss-EDI is to dope proteins inside helium droplets and collect a diffraction...
Chalaniline A, an unusual xanthone-like aminofulvene with modest cytotoxicity, and chalaniline B [1-anilino-2,8-dihydroxy-3-(hydroxymethyl)xanthone], an antibacterial aminoxanthone, were previously isolated by Loesgen and coworkers from vorinostat-treated Chalara sp. 6661. Of note, the anilino moiety found within both chalaniline structures originates from biotransformation of the HDAC inhibitor vorinostat (SAHA, suberanilohydroxamic acid) by...
