Journal ArticleDOI
Palladium-catalysed transannular C–H functionalization of alicyclic amines
TL;DR: This work uses the boat conformation of the substrates to achieve palladium-catalysed amine-directed conversion of C–H bonds to C–C bonds on various alicyclic amine scaffolds, and demonstrates this approach by synthesizing new derivatives of several bioactive molecules, including varenicline.
Journal ArticleDOI
Nickel-catalysed anti-Markovnikov hydroarylation of unactivated alkenes with unactivated arenes facilitated by non-covalent interactions.
TL;DR: The first undirected hydroarylation of unactivated alkenes with unactivated arenes that occurs with high regioselectivity for the anti-Markovnikov product is reported, achieved with high selectivity by using nickel catalysts bearing large N-heterocyclic carbene ligands.
Journal ArticleDOI
Mechanistic Investigations of the Hydrogenolysis of Diaryl Ethers Catalyzed by Nickel Complexes of N-Heterocyclic Carbene Ligands.
Noam I. Saper,John F. Hartwig +1 more
TL;DR: Detailed mechanistic analysis of the hydrogenolysis of diaryl ethers catalyzed by the combination of Ni(COD)2 (COD = 1,5-cyclooctadiene) and an N-heterocyclic carbene (NHC) and NaOt-Bu was found to deprotonate the phenol product and to prevent formation of inactive NiI dimers.
Journal ArticleDOI
Effect of ligand modification on the reactivity of phosphinoamide-bridged heterobimetallic Zr/Co complexes
TL;DR: The effect of modifying the N-aryl substituent of the phosphinoamide ligands linking Zr and Co in tris(phosphinoamide)-linked heterobimetallic complexes has been investigated and reveals similar structural features but with a less sterically hindered Zr apical site in complex 4.
Journal ArticleDOI
2,2,6,6-Tetramethylpiperidine-Catalyzed, Ortho-selective Chlorination of Phenols by Sulfuryl Chloride
Noam I. Saper,Barry B. Snider +1 more
TL;DR: Ortho-selective chlorination is successful even with electron deficient phenols such as 2-hydroxybenzaldehyde and 2'-hydroxyacetophenone, and Notably, ortho selectivity increases with the reaction temperature.
