An Exploratory Study of Regiocontrol in the Heck Type Reaction. Influence of Solvent Polarity and Bisphosphine Ligands

Autor: Björn Åkermark, Maik Ludwig, Mats Svensson, Staffan Strömberg

Publikováno v: Organometallics. 18:970-975

The regiochemistry of the addition of arylpalladium species to styrene and propene has been studied. It was found that for the reaction of P2Pd(Ph)X the counterion X, the polarity of the solvent, a...

Protonation of π-alkene–rhodium(I) complexes leads to σ-alkyl–rhodium(III)—an NMR study

Autor: Lars Öhrström, Julius Glaser, Krister Zetterberg, Staffan Strömberg

Publikováno v: Journal of Organometallic Chemistry. 558:123-130

The reaction of Rh(beta-diketonato)(alkene)(2) complexes with CF3SO3H in THF gives Rh(beta-diketonato)(alkyl) species when the alkene is ethylene, cis-butene or 5-methylene-cycloheptene whereas 1,5-cyclooctadiene complexes are unreactive. The reactio
