Organocatalytic C–H hydroxylation with Oxone® enabled by an aqueous fluoroalcohol solvent system
Published in Advances in Chemical Engineering and Science
Selective hydroxylation of 3° and benzylic C–H bonds is made possible using a non-metal-based catalyst system, Oxone as the terminal oxidant, and an aqueous fluoroalcohol solvent mixture. The choice of solvent is uniquely effective for this process, but seemingly at odds with our finding that H2O promotes reduction of the oxaziridine intermediate. ...
Speciation and decomposition pathways of ruthenium catalysts used for selective C–H hydroxylation
Published in Advances in Chemical Engineering and Science
Mechanistic insight into a C–H hydroxylation reaction catalysed by [(Me3tacn)RuCl3] has been obtained using desorption electrospray ionization mass spectrometry (DESI-MS) to identify reactive intermediates and to determine the fate of the starting metal complex. Our studies provide direct evidence for the formation of a high-valent dioxo-Ru(VI) spe...
Non-Directed Allylic C-H Acetoxylation in the Presence of Lewis Basic Heterocycles.
Published in Chemical science
We outline a strategy to enable non-directed Pd(II)-catalyzed C-H functionalization in the presence of Lewis basic heterocycles. In a high-throughput screen of two Pd-catalyzed C-H acetoxylation reactions, addition of a variety of N-containing heterocycles is found to cause low product conversion. A pyridine-containing test substrate is selected as...
