Displacement reactions and fluorescence studies of boroxine amine complexes 2011 3027 The Boron atom has seen an increase in usefulness over the last half century due in part to the unique properties of boron that allow for dative binding. Aspects of the boron-nitrogen bond were examined through both displacement reactions, which w...
Synthesis and characterization of boron-nitrogen datively bonded supramolecular assemblies and rotors 2012 1852 The synthesis of three adducts of ferrocene boroxine (C10H9Fe)3B3O3 with dative bonds to amines (pyridine, 4-picoline, 4-aminomethyl pyridine, and p-bromoaniline), as well as to two diamines (4,4-bipyridine and 1,4-diazabicyclo[2.2.2]octane) to for...
Boronate macrocycle formation using boron-Lewis base dative bonds and boronic acid-diol condensation reactions 2013 3899 Synthesis of boronate ester compounds via condensation reactions using either an amine or an amine N-oxide coupled with a boronic acid. Synthesis of boronate ester compounds using quinoline isomers coupled with 2, 3-dihydroxynaphthalene was also atte...
(2)rotaxanes as reagents for (3)rotaxane sythesis [i.e. synthesis] 2010 1765 It was our hope to demonstrate that fairly simple systems such as a [2]rotaxane can itself be used as a reagent to synthesize even larger systems such a [3]rotaxane. This modular type approach offers several advantages over alternative methods. The [...
Synthesis and complexation of boronic acid derivatives with nitrogen- and phosphorous-oxides 2021 31 I would like to thank my thesis research advisory committee for their guidance, patience, and advice throughout the process of completing my thesis. Specifically, I would like to thank Dr. William Kwochka for the encouragement and teachings that he h...
Selective reduction of aromatic esters using in-situ-generated?LiBH4 2020 98 Functional group interconversion is an essential strategy in synthetic organic chemistry with some functional groups being more difficult to. The ester functional group is relatively difficult to reduce when compared to aldehydes and ketones. Typical...
Phenyl replacement reactions: solvent effects on reactions of boroxines with primary amines 2015 1615 When primary amines are reacted with boroxines in solvents such as diethyl ether or THF, a dative bond forms between the lone pair of electrons on the nitrogen atom and a boron atom in a predictable manner. However, when the highly complexing solvent...
