Abstract

original image

Katalysatoren mit Biss: Chirale PdII-Komplexe wurden mit dreizähnigen Liganden aus N-heterocyclischem Carben, Amidat und Alkoxid hergestellt. Dimere und monomere Formen dieser Komplexe lassen sich durch Einwirkung von Säuren und Basen ineinander umwandeln (siehe Schema). Die Katalysatoren sind in asymmetrischen Heck-Reaktionen aktiv und ergeben deutlich bessere Enantioselektivitäten als bisherige Methoden.
