Metal hydroquinone complexes: The physical properties and catalysis of rhodium & iridium quinonoids. - 167 p.

Adviser: William Trenkle.

Thesis (Ph.D.)--Brown University, 2008.

Metal hydroquinone species offer a versatile and multifunctional approach to transition metal catalysis through the facile transformation of the eta 6-hydroquinone to the eta4-benzoquinone. After its initial discovery, a novel rhodium hydroquinone complex was used to efficiently catalyze the formation of carbon-carbon bonds through a number of different reactions, most notably the 1,4 conjugate addition of arylboronic acids to alpha,beta-unsaturated carbonyl compounds. The rhodium hydroquinone showed excellent activity for a range of substrates, including a variety of boronic acids, and several unsaturated compounds containing either alpha- or beta-di-substitution.

520 $a Metal hydroquinone species offer a versatile and multifunctional approach to transition metal catalysis through the facile transformation of the eta 6-hydroquinone to the eta4-benzoquinone. After its initial discovery, a novel rhodium hydroquinone complex was used to efficiently catalyze the formation of carbon-carbon bonds through a number of different reactions, most notably the 1,4 conjugate addition of arylboronic acids to alpha,beta-unsaturated carbonyl compounds. The rhodium hydroquinone showed excellent activity for a range of substrates, including a variety of boronic acids, and several unsaturated compounds containing either alpha- or beta-di-substitution.
520 $a Following its catalytic development, a number of 1H NMR studies were undertaken in order to determine the physical properties of the rhodium quinonoid species in solution. Besides examining the effects of different gases and bases on the reactivity and stability of the rhodium complexes, various hydroxylated arenes, including a chiral hydroquinone ligand, were investigated as replacement ligands for the hydroquinone with the intent of improving the original catalyst system and developing an asymmetric catalyst. As a final comparison, an iridium hydroquinone complex was studied spectroscopically and used in the first reported iridium catalyzed 1,4 conjugate addition reaction.
