Creator:: Naffziger, Michael R.
Abstract:: The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

Creator:: Zhao, Peng
Abstract:: This dissertation describes the racemic and enantioselective synthesis cavicularin. Cavicularin is a macrocyclic bisbibenzyls family member natural product. It has been an attractive synthetic target due to its intriguing structure: the macrocyclic core imparts sufficient strain on the system to force one benzene rings to adopt a boat-shaped conformation, out...

Abstract:: A survey of the methods of purification of KC1, for use in preparing single crystals by growth from the melt, was made. Two methods, fractional recrystallization and ion exchange, were used. The purity of the salt and crystals grown from the same salt were compared with the findings of other...

Abstract:: The electrochemistry of the lithium-potassium-sodium carbonate-borate melt was explored by voltammetry and chrono-amperometry. In support of this, a controlled-potential polarograph and associated hardware was constructed. Several different types of reference electrodes were tried before choosing a porcelain membrane electrode containing a silver wire immersed in a silver sulfate melt. The...

Creator:: Truska, Scott
Abstract:: A three part study involving aspects of radical properties of various aromatic species was accomplished. Experiments to ascertain the importance of geometric and electronic effects on the intramolecular transfer of a pi-complexed radical to a terminal double bond was performed. Several 4-aryl-1-butenes were reacted in competition with 1-undecene with a...

Creator:: Shaw, Subrata
Abstract:: 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...
