Katalysatoraktivierung als Schlüsselfaktor in Kreuzkupplungen: Raumtemperatur‐Kupplungen schwacher Nukleophile ermöglicht durch [Pd(1‐MeNAP)TFA]2 Präkatalysatoren

open access: yesAngewandte Chemie, EarlyView.
Bei vielen Pd‐katalysierten Kreuzkupplungen hat sich gezeigt, dass die Katalysatorleistung durch dessen Aktivierung begrenzt wird. Methylnaphthyl (MeNAP)‐Palladiumtrifluoracetat‐Dimere werden als leicht zu lagernde und handhabende Präkatalysatoren vorgestellt, die sich unter Reaktionsbedingungen schnell aktivieren, selbst wenn nur schwach ...
