Fall 2015
In response to an increasing global need for inexpensive, energy efficient electronics, the field of organic semiconductors has experienced tremendous growth over the last 3 decades. In addition to their low cost, and interesting electronic and optical properties, organic semiconductors offer the...

Investigating the 197Au-31P spin-spin coupling interactions in gold-phosphine halides using solid-state nuclear magnetic resonance, spectral simulations, and quantum chemistry computations
DownloadSpring 2011
Phosphorus-31 nuclear magnetic resonance spectroscopy with magic angle spinning was used to characterize 197Au-31P spin-spin coupling interactions in solid gold-phosphine halides and the spectra have been analyzed using perturbation theory. The 197Au nucleus has a natural abundance of 100%, a...

Improved Gram-Scale Procedure for MIBA-Catalyzed Direct Amidation and Its Application to the Preparation of alpha and beta Peptides
DownloadFall 2015
Direct condensation between a carboxylic acid and amine must overcome the initial formation of a thermodynamically stable and unreactive carboxylate-ammonium salt, providing the amide product only at very high temperatures (over 160 oC) that are incompatible with many functionalized molecules....

Seven- and Eight-Membered Ether Formation via Sulfonium Ylide Rearrangement Processes and Application in an Approach to (+)-Laurencin
DownloadSpring 2010
Given the large number of biologically active natural products containing medium-sized ether motifs, many organic chemists have shown great interest for developing new methodologies to access these structures. In particular, numerous synthetic methodologies for the construction of seven-membered...
