The preparation of holocellulose accurately and rapidly is very
important to study the nature and relationships of the carbohydrate
components and the substituent groups, acetyl, carboxyl, and methoxyl.
In as much as bromine was thought to be less destructive to
wood than chlorine, it was decided to attempt to isolate...
An atmospheric pressure argon glow discharge is shown
to detect trace levels of carbohydrates in aqueous flowing
systems, using either of two glow discharge solution
interface configurations. The first configuration consists
of an oscillating glow discharge sustained between a flowing
aqueous cathode and platinum anode. Picomole and micromolar
mass and...
The Disney Princesses are some of the most beloved and well-recognized characters in animation across the globe. Most of these characters sing throughout their movie. This essay analyzes what I refer to as the “I Want” song of several Disney Princesses. It is divided into three sections, one for each...
A large-scale preparative method for potassium di-n-butylborate
in triethylamine solvent has been developed. The reaction of
potassium di-n-butylborate I with trifluoromethyl iodide has been
shown to yield trifluoromethyl di-n-butylborane and other products.
Reaction of this substance with boron trifluoride gave trifluoromethyl
boron difluoride. Reactions of diboron tetrafluoride, boron tribromide,
and...
This thesis describes the development of a new enantioselective synthetic method employing chiral cis-2,5-diaminobicyclo[2.2.2]octane-based organometallic catalysts. The significance of this new method to organic synthesis is illustrated with preparation of enantioenriched products that are transformed to important pharmaceutical agents. Chapter 1 provides a brief historical overview of asymmetric catalysis, especially...
Aromatic heterocycles are core structural motifs in natural products, pharmaceuticals and biological polymers. Indoles, in particular, represent a significant subclass of aromatic heterocycles, both in terms of sheer numbers, but also in biological and pharmaceutical relevance. As such, new methodologies for the synthesis of indoles represent an important and continually...
The design and construction of two new sample injection systems or nozzles, for use with the Oregon State electron diffraction apparatus are discussed. One of these nozzles was intended for use with volatile samples the vapors of which were to be heated or cooled over the range -196 to 540°C;...
