Partially-Fluorinated Polyimides using Aliphatic Diamines
… of partially-fhiorinated polyimides made using aliphatic diamines as the flexible component and titaniumdioxide nanoparticles were synthesized. All of the reactions were performed via condensation polymerization. Thermal data suggest that the obtained films have thermal stability between 395 - …

Polarography of mercury in aliphatic diamines
<p>The problem taken for investigation was discovered when a cryostat needed for use in polarography in liquid ammonia (the original problem) was found broken. For experience it was decided to turn to another form of nonaqueous polarography while the parts were on order. Materials remaining from a …

Synthesis of Resveratrol Esters and Aliphatic Acids.
… been made to design and synthesize RV esters and aliphatic acids in an attempt to increase its bioavailability, solubility in water, and possibly improving its biological activities. Resveratrol esters, 3,5,4'-triacetyloxystilbene <b>(2)</b> and Methyl 1,1',1''- (3,4',5-stilbenyl)-1,6-hexanedioate …

Reductive metabolism of aliphatic tertiary amine n-oxides.
… a proposal concerning the feasibility of using aliphatic tertiary amine N-oxides as antiarrhythmic agent prodrugs. Lignocaine was selected as a candidate for prodrug development, because the N-oxide is a non-active, polar derivative of lignocaine and the drug of choice for ventricular …

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 …

Aliphatic Nitroxyl Radicals as Antifatigue Agents for Rubbers
The antifatigue activity of hindered nitroxyl radicals and their precursors have been studied. It was demonstrated that hindered alicyclic nitroxyl radicals and their precursors have weak antifatigue activities. However the trend increased in the order: amine < nitroxyl radical < hydroxylamine. The …

Radical methods for the synthesis of aliphatic amines
The aliphatic amine motif is a ubiquitous and uniquely important functional group in pharmaceutical agents and the development of ever more efficient synthetic methods for their synthesis is a continuous challenge. This thesis details the development of three new radical reactions for the synthesis …

Electrochemical Detection of Aliphatic Sulfur Compounds in Liquid Coal Extracts
… Organosulfur compounds such as sulfides, aliphatic thiols, and disulfides were studied using reverse phase HPLC with electrochemical detection in a acetonitrile/water mobile phase. Coal samples IBC 101 and IBC 105 were extracted with THF and hexane. The liquid coal extracts were …

New strategies for the synthesis and functionalization of aliphatic amines
The invention of catalytic processes that convert feedstock chemicals into pharmacologically-privileged amines is a landmark challenge in organic synthesis. This thesis describes the development of three novel transition-metal catalyzed processes for the synthesis of alkylamines that attempts to …

Photoredox activation of carbon dioxide and unactivated aliphatic carbonyl compounds
Chapter 1: Photoredox Activation of Carbon Dioxide for Amino Acid Synthesis in Continuous Flow. Although carbon dioxide (CO₂ ) is highly abundant, its low reactivity has limited its use in chemical synthesis. In particular, methods for carbon-carbon bond formation generally rely on two-electron …

The Reactions of Ethyl Ethoxymagnesiomalonate With Some Simple Aliphatic Diacid Chlorides.
Due to the biochemical and pharmacological interest in cyclitols, alone, and in combination with other molecules, the biosynthesis of these compounds has been studied in a number of laboratories. Kiely and Sherman recently developed a chemical model which describes the proposed mechanism for the …
