Bis(cyclopropenium)phosphines: Synthesis, Reactivity, and Applications

Autor: Jonathan W. Dube, Manuel Alcarazo, Gerlinde Mehler, Javier Carreras, Alessandro Zanardi, Pawel Linowski

Publikováno v: Chemistry - A European Journal. 22:15320-15327

A straightforward route for the preparation of a set of bis(cyclopropenium)-substituted phosphines is reported. Due to their dicationic nature, these ligands depict an excellent π-acceptor character. The effect of the ligand substituent pattern on t

Palladium-Catalysed Amination of Aryl- and Heteroaryl Halides Usingtert-Butyl Tetraisopropylphosphorodiamidite as an Easily Accessible and Air-Stable Ligand

Autor: Manfred T. Reetz, Gerlinde Mehler, Gheorghe-Doru Roiban

Publikováno v: European Journal of Organic Chemistry. 2014:2070-2076

The phosphorus compound tert-butyl tetraisopropylphosphorodiamidite, prepared from bis(diisopropylamino)chlorophosphine, is an excellent ligand for palladium-catalysed Buchwald–Hartwig amination of aryl- and heteroaryl chlorides and bromides. Based

Mixtures of chiral and achiral monodentate ligands in asymmetric Rh-catalyzed olefin hydrogenation: reversal of enantioselectivity

Autor: Manfred T. Reetz, Gerlinde Mehler

Publikováno v: Tetrahedron Letters. 44:4593-4596

The recently described method of combinatorial asymmetric transition metal catalysis based on the use of mixtures of chiral monodentate P-ligands has been extended to include mixtures of chiral and achiral monodentate P-ligands, reversal of enantiose

Mixtures of chiral monodentate phosphites, phosphonites and phosphines as ligands in Rh-catalyzed hydrogenation of N-acyl enamines: extension of the combinatorial approach

Autor: Andreas Meiswinkel, Manfred T. Reetz, Gerlinde Mehler

Publikováno v: Tetrahedron: Asymmetry. 15:2165-2167

Mixtures of BINOL-derived monodentate phosphites and phosphonites have been reacted with Rh-salts to form three (pre)catalysts, which are in equilibrium; two homo-combinations ML a L a and ML b L b as well as the hetero-combination ML a L b . In thes
