The Preparation And Characterization Of Tetrafluoro-Lambda~6~-Sulfanes, Linbin Zhong
The Preparation And Characterization Of Tetrafluoro-Lambda~6~-Sulfanes, Linbin Zhong
Legacy Theses & Dissertations (2009 - 2024)
Synthetic access to systematically substituted tetrafluoro-λ6-sulfanes was challenging and the research in this area had been largely abandoned. The original reports of disubstituted-tetrafluoro-λ6-sulfanes were limited to substitution by diphenyl and dialkyl groups. The dialkyl-tetrafluoro-λ6-sulfanes were reactive while the diphenyl substituted compounds showed decreased reactivity. In this dissertation, the systematic substitution on tetrafluoro-λ6-sulfanes has enabled the studies of the substitution effects on reactivity.
Iodine-Initiated Hydration Of Internal Alkynes, Nicholas J. Shuber, Karelle Aiken
Iodine-Initiated Hydration Of Internal Alkynes, Nicholas J. Shuber, Karelle Aiken
Honors College Theses
The iodine-initiated hydration of internal alkynes is a novel, green, and inexpensive synthetic pathway in comparison with the commonly used transition metal catalyzed reactions. This can be a useful alternative in many fields, academic or industrial. This experimental design has been used successfully on terminal alkynes and is now being extended to internal alkynes. Through systematic probing of the reaction conditions, we have gleaned sufficient information to determine a strong mechanistic hypothesis based on neighboring group participation. Here in, we will report our result with a series of internal, keto alkynes reacted under ambient conditions with iodine in “wet” solvent. …
