Frustrierte Lewis‐Paare: metallfreie Wasserstoffaktivierung und mehr
Abstract
Die Kombination sterisch gehinderter Lewis‐Säuren und ‐Basen führt nicht zur üblichen Neutralisationsreaktion unter Bildung der “klassischen” Lewis‐Säure/Base‐Addukte. Stattdessen stehen die Lewis‐Acidität und ‐Basizität solcher “frustrierten Lewis‐Paare” (FLPs) gemeinsam für die Durchführung ungewöhnlicher Reaktionen zur Verfügung. Typische Beispiele für FLPs bestehen aus inter‐ und intramolekularen Kombinationen sperriger Phosphine und Amine mit stark elektrophilen RB(C 6 F 5)2‐Komponenten. Viele frustrierte Lewis‐Paare sind in der Lage, Wasserstoff heterolytisch zu spalten. Die resultierenden H+/H−‐Paare (z. B. stabilisiert in Form der entsprechenden Phosphonium‐Kation/Hydridoborat‐Anion‐Salze) fungieren als metallfreie Katalysatoren für die Hydrierung sperriger Imine, Enamine, Enolether usw. FLPs reagieren auch mit Alkenen, Carbonylverbindungen und einer Vielzahl anderer kleiner Moleküle, darunter auch Kohlendioxid, in vermutlich kooperativen Dreikomponentenreaktionen. Auf dieser Beobachtung lassen sich neue Synthesestrategien aufbauen.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
