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 ...

Funktionalisierung von Peptiden auf der festen Phase im späten Synthesestadium

open access: yesAngewandte Chemie, EarlyView.
Peptidmodifikationen sind für die Kontrolle der Eigenschaften von Peptidwirkstoffen von entscheidender Bedeutung. Daher sind Strategien, die einen effizienten und schnellen Einbau nicht‐kanonischer Modifikationen in Peptide in Parallelformaten ermöglichen, sehr gefragt.

Eine Interphase mit ortsfesten Ladungen synchronisiert den Ionentransport und unterdrückt raumladungsgetriebene Ineffizienz unter räumlicher Begrenzung auf Nanoliter‐Volumina

open access: yesAngewandte Chemie, EarlyView.
Die elektrochemische Energiespeicherung stößt bei extremer Miniaturisierung an fundamentale Grenzen, da Grenzflächen‐ und Raumladungseffekte dominieren. Hier stellen wir eine selektive Interphase mit ortsfesten Ladungen in einer Zwillingsrohr‐μ‐Swiss‐Roll‐Architektur vor.
