“…[191] Activities and selectivities of the individual systems are strongly dependent on the steric properties of the phosphane and the nature of the respective phosphane/surfactant combination. In each case the presence of CO 2 is necessary.…”

“…Monflier et al [18] examined the effect of trialkylamines on biphasic water telomerizations. They reported that [a] T = 90 8C, t = 1.5 h, n But.…”

“…[49] Beller et al used in situ generated carbene ligands in the palladium-catalyzed telomerization of isoprene with methanol. The carbene ligand was 1,3-dimesitylimidazolium mesylate (18). [12] The main telomeric product formed was the head-to-head telomer with selectivities between 70-80 %.…”

“…Der Hauptunterschied liegt darin, dass Isopren ein asymmetrisches 1,3-Dien ist, woraus vier verschiedene Verknüpfungsarten resultieren, von denen jede noch zum n-oder iso-Telomer führen kann. Schema [16,17] Diese Carbonate seien bessere Nucleophile als Wasser und bildeten unter Eliminierung von CO 2 Octadienole (Schema 5). Diese Annahme wird dadurch bestätigt, dass kein zusätzliches Lö-sungsmittel oder CO 2 benötigt wird, [18] wenn die Telomerisation in Gegenwart von Additiven wie Na 2 CO 3 , K 2 CO 3 oder KHCO 3 erfolgt.…”

“…Monflier et al [18] [2,25] Die Regioselektivität der Reaktion kann durch den Einsatz von in situ generierten Palladium(0)-Carben-Komplexen, die aus Imidazoliumsalzen (6) hergestellt werden, verbessert werden. [26][27][28] Grundsätzlich können Ausbeute, Selektivität und Turnover-Zahl (TON) durch den Einsatz von Carbenliganden erhöht werden (Tabelle 2).…”
