Webb11 juni 2008 · We have developed a new site-selective Cu(II)-catalyzed C−H bond functionalization process that can selectively arylate indoles at either the C3 or C2 position under mild conditions. The scope of the arylation process is broad and tolerates broad functionality on both the indole and aryl unit, which makes it amenable to further … Webb21 juni 2024 · Face to Face with Robert J. Phipps. Robert J. Phipps studied Chemistry at Imperial College London in 2006 and then moved to the University of Cambridge to complete his PhD (2010) with Prof. Matthew Gaunt on the development of new copper-catalysed arylation reactions. Since then, he has worked at the University of California, …
