Journal ArticleDOI
Monodentate Phosphines Provide Highly Active Catalysts for Pd-Catalyzed C ? N Bond-Forming Reactions of Heteroaromatic Halides/Amines and (H)N-Heterocycles
Journal ArticleDOI
Copper-catalyzed N-arylation of imidazoles and benzimidazoles.
TL;DR: 4,7-Dimethoxy-1,10-phenanthroline (L1c) was found to be an efficient ligand for the copper-catalyzed N-arylation of imidazole and benzimidazoles with both aryl iodides and bromides under mild conditions and the addition of poly(ethylene glycol) accelerates this reaction.
Journal ArticleDOI
4,7-Dimethoxy-1,10-phenanthroline: An Excellent Ligand for the Cu-Catalyzed N-Arylation of Imidazoles
TL;DR: 4,7-Dimethoxy-1,10-phenanthroline was found to be an efficient ligand for the copper-catalyzed N-arylation of imidazole with aryl iodides and bromides under mild conditions.
Journal ArticleDOI
Palladium-Catalyzed Enantioselective α-Arylation and α-Vinylation of Oxindoles Facilitated by an Axially Chiral P-Stereogenic Ligand
TL;DR: The enantioselective alpha-arylation and alpha-vinylation of oxindoles catalyzed by Pd and a biarylmonophosphine ligand with both axial and phosphorus-based chirogenicity is reported.
Journal ArticleDOI
An improved Cu-based catalyst system for the reactions of alcohols with aryl halides.
TL;DR: The use of 3,4,7,8-tetramethyl-1,10-phenanthroline (Me(4)Phen) as a ligand improves the Cu-catalyzed cross-coupling reactions of aryl iodides and bromides with primary and secondary aliphatic, benzylic, allylic, and propargylic alcohols.
