Palladium-Catalyzed Carbonylations of Aryl Bromides using Paraformaldehyde: Synthesis of Aldehydes and Esters
Autor: Kishore Natte, Helfried Neumann, Andreas Dumrath, Matthias Beller
Publikováno v: Angewandte Chemie. 126:10254-10258
Carbonylation reactions represent useful tools for organic synthesis. However, the necessity to use gaseous carbon monoxide is a disadvantage for most organic chemists. To solve this problem, novel protocols have been developed for conducting palladi

Autor: Andreas Dumrath, Christa Lübbe, Matthias Beller, Helfried Neumann, Renat Kadyrov, Ralf Zimmermann, Marion Schäffer
Publikováno v: ChemCatChem. 6:684-688
The dramatic effect of substrate impurities on the performance of a specific ruthenium catalyst system is demonstrated in the benchmark metathesis reaction of diethyl diallylmalonate. Based on detailed two-dimensional GC–time-of-flight MS measureme

Autor: Matthias Beller, Thomas Schulz, Andreas Dumrath, Helfried Neumann, Stephan Enthaler, Benjamin Schäffner, Anke Spannenberg, Armin Börner, Christian Torborg
Publikováno v: Chemistry - A European Journal. 15:4528-4533
A new robust palladium/phosphine catalyst system for the selective monoarylation of ammonia with different aryl bromides and chlorides has been developed. The active catalyst is formed in situ from [Pd(OAc)(2)] and air- and moisture-stable phosphines
