Ligand-controlled highly regioselective and asymmetric hydrogenation of quinoxalines catalyzed by ruthenium N-heterocyclic carbene complexes.
Optically active six-membered rings such as cyclohexanes and piperidines play an important role as biologically active building blocks and key intermediates in organic chemistry. Catalytic asymmetric hydrogenation of aromatic and heteroaromatic compounds is one of themost straightforward routes for the formation of these saturated or partially saturated molecules. Recently, tremendous progress ...
متن کاملN-Heterocyclic Carbene-Palladium and -Copper Complexes in Cross-Coupling Reactions
Chapter 1 gives the reader a background on cross-coupling reactions, in particular palladium mediated couplings. Furthermore the importance of ligands, including phosphines and N-heterocyclic carbenes (NHC), in such cross-coupling reactions is explored. Chapter 2 provides a background to the reductive lithiation of phosphines, followed by an account of our investigation of BINAP functionalisati...
متن کاملThiazolium-derived N-heterocyclic carbene-catalyzed cross-coupling of aldehydes with unactivated imines.
Cross-coupling of aromatic aldehydes or benzoins with unactivated imines catalyzed by an N-heterocyclic carbene (NHC) affords alpha-amino ketones smoothly.
متن کاملCopper N-heterocyclic carbene (NHC) complexes as carbene transfer reagents.
A method is described that makes use of easily prepared, inexpensive copper synthons as N-heterocyclic carbene (NHC) transfer agents to generate catalytically relevant gold and palladium complexes.
متن کاملBent metal carbene geometries in amido N-heterocyclic carbene complexes.
Lithium(I) and uranium(VI) amido-tethered Bu(t)-substituted N-heterocyclic carbene (NHC) complexes exhibit very distorted metal-carbene bonds; the corresponding magnesium(II) and mesityl-substituted NHC uranium(VI) complexes are undistorted; the distortion does not affect the ligand binding strength, suggesting a dominance of electrostatic character in closed-shell electropositive metal-carbene...
