|(2)rotaxanes as reagents for (3)rotaxane sythesis [i.e. synthesis]
||It was our hope to demonstrate that fairly simple systems such as a rotaxane can itself be used as a reagent to synthesize even larger systems such a rotaxane. This modular type approach offers several advantages over alternative methods. The [...
|Displacement reactions and fluorescence studies of boroxine amine complexes
||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
||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
||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...
|Phenyl replacement reactions : solvent effects on reactions of boroxines with primary amines
||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...
