Trispyrazolylborate and Tetramethylcyclopentadienyl Osmium Chemistry: Toward Methane Coordination Complexes
Treatment of H2OsBr6 with 4 equiv. of tetramethylcyclopentadiene (C5Me4H2) in tert-butanol affords [(C 5Me4H)2OsBr]2[Os2Br 8]. The brown color of the salt suggests that the anion adopts an eclipsed conformation (D4h symmetry) and this conclusion has been confirmed by a single-crystal X-ray …

Microwave-assisted Synthesis of Modified Cyclopentadienyl Iridium and Rhodium Chloro-bridged Dimers
The present work describes the design and synthesis of a series of dimers [(η5 - ring)MCl]2(μ2 -Cl)2, (where (η5 -ring)MCl = (η5 -Me4C5R)Rh(III)Cl or (η5 -Me4C5R)Ir(III)Cl). Iridium and rhodium dimeric complexes were synthesized via a microwave reaction and directly compared through single-crystal …

Design and Modification of Half-Sandwich Ir(III), Rh(III), and Ru(II) Amino Acid Complexes for Application in Asymmetric Transfer Hydrogenation Reactions
This dissertation describes the design and synthesis of a series of half-sandwich amino acid complexes of the form), (aa = α-amino carboxylate), and their utility as asymmetric transfer hydrogenation catalysts of ketones. Variation of the metal center, the n-ring, and the aa was used to tune these …
