“…Ligands such as R‐C 6 (CF 3 ) 5 with R=H, OH, CH 3 , NH 2 are highly promising candidates to form novel WCAs or LAs. Other promising Lewis acids are the potentially tunable FcB(OCH(CF 3 ) 3 ) 2 and 1,1′‐(B(OCH(CF 3 ) 3 ) 2 ) 2 Fc (Fc=ferrocene) or the bulky compounds of the type B(C 6 F 5 )RR′ (R=C 6 F 5 , R′=Me 3 SiCH(C 6 F 5 ); R=R′=Me 3 SiCH(C 6 F 5 ); R=Me 3 SiCH(C 6 F 5 ), R′=Me 3 SiCH(C 6 H 5 ); R=C 6 F 5 , R′=CH(C 6 F 5 ) 2 ; R=Cl, R′=Ph 2 C(C 6 F 5 ); R=C 6 F 5 O, R′=Me 3 SiCH(C 6 F 5 ); Figure ) . By adjusting the steric and electronic influence of the ligands, the novel electron‐deficient tris(aryl)boranes, B(C 6 F 5 ) 3− n (C 6 Cl 5 ) n ( n= 1–3) were synthesized and characterized .…”

This Review gives a comprehensive overview of the most topical weakly coordinating anions (WCAs) and contains information on WCA design, stability, and applications. As an update to the 2004 review, developments in common classes of WCA are included. Methods for the incorporation of WCAs into a given system are discussed and advice given on how to best choose a method for the introduction of a particular WCA. A series of starting materials for a large number of WCA precursors and references are tabulated as a useful resource when looking for procedures to prepare WCAs. Furthermore, a collection of scales that allow the performance of a WCA, or its underlying Lewis acid, to be judged is collated with some advice on how to use them. The examples chosen to illustrate WCA developments are taken from a broad selection of topics where WCAs play a role. In addition a section focusing on transition metal and catalysis applications as well as supporting electrolytes is also included.

Die Schöne (WCA) und das (kationische) Biest: Neues aus der Chemie von und mit schwach koordinierenden Anionen

An einen Übersichtsartikel aus dem Jahre 2004 anknüpfend, wird hier über den strukturellen Aufbau, die Stabilität und die Anwendungen moderner schwach koordinierender Anionen (weakly coordinating anions, WCAs) berichtet, aber auch über Fortschritte der “klassischen” WCAs. In tabellarischer Form werden sowohl Ausgangsverbindungen zur Einführung einer Vielzahl von WCAs als auch deren physikochemische Eigenschaften zusammengefasst. Damit lässt sich für mögliche Anwendungen gut beurteilen, wie WCAs am besten in vorgegebene Systeme inkorporiert werden können. Die angeführten Anwendungsbeispiele für WCAs sind breit gestreut, eigene Abschnitte bilden aber die Schwerpunkte Übergangsmetallkomplexe, katalytische Anwendungen und Leitsalze für elektrochemische Anwendungen.
