Ru0 or RuII: A Study on Stabilizing the 'Activated' Form of Ru-PNP Complexes with Additional Phosphine Ligands in Alcohol Dehydrogenation and Ester Hydrogenation

Autor: Ansgar Schäfer, Daniel J. Tindall, Rocco Paciello, A. Stephen K. Hashmi, Frank Rominger, Thomas Schaub, Peter Comba, Mathias Schelwies, Maximilian Menche

Publikováno v: Inorganic Chemistry. 59:5099-5115

The complex Ru-MACHO has been previously shown to undergo uncontrolled degradation subsequent to base-induced dehydrochlorination in the absence of a substrate. In this study, we report that stabil...

Mechanistic Investigation of the Nickel-Catalyzed Carbonylation of Alcohols

Autor: Tamal Ghosh, A. Stephen K. Hashmi, Katharina Rück, Ansgar Schäfer, Rocco Paciello, Saskia Krieg, Sara Sabater, Thomas Schaub, Maximilian Menche, Peter Comba

Publikováno v: Organometallics. 39:870-880

The carbonylation of alcohols represents a straightforward and atom-efficient methodology for the preparation of carboxylic acids. It is desirable to perform these reactions under precious metal-fr...

Phosphine-Catalyzed Vinylation at Low Acetylene Pressure

Autor: Ansgar Schäfer, Pavel Tužina, Maximilian Menche, A. Stephen K. Hashmi, Peter Comba, Frank Bienewald, Thomas Schaub, Nikolai A. Sitte, Frank Rominger

Publikováno v: The Journal of organic chemistry. 86(18)

The vinylation of various nucleophiles with acetylene at a maximum pressure of 1.5 bar is achieved by organocatalysis with easily accessible phosphines like tri-n-butylphosphine. A detailed mechanistic investigation by quantum-chemical and experiment

Intercepting the Disilene-Silylsilylene Equilibrium

Autor: Julia I. Schweizer, Gary S. Nichol, Michael J. Cowley, Maximilian Menche, Max C. Holthausen, Martin W. Stanford

Publikováno v: Stanford, M W, Schweizer, J I, Menche, M, Nichol, G S, Holthausen, M C & Cowley, M J 2019, ' Intercepting the Disilene-Silylsilylene Equilibrium ', Angewandte Chemie International Edition, vol. 58, no. 5, pp. 1329-1333 . https://doi.org/10.1002/anie.201810056

The equilibrium between disilenes (R2 Si=SiR2 ) and their silylsilylene (R3 Si-SiR) isomers has previously been inferred but not directly observed, except in the case of the parent system H2 Si=SiH2 . Here, we report a new method to prepare base-coor
