The history of silyl cations has all the makings of a drama but with a happy ending. Being
considered reactive intermediates impossible to isolate in the condensed phase for …

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 …

IUPAC defines Lewis acidity as the thermodynamic tendency for Lewis pair formation. This
strength property was recently specified as global Lewis acidity (gLA), and is gauged for …

The computed fluoride ion affinity (FIA) is a valuable descriptor to assess the Lewis acidity of
a compound. Despite its widespread use, the varying accuracy of applied computational …

Lewis acids play a major role in all areas of chemistry. For a long time, toxic, corrosive and
oxidizing SbF5 was considered as the strongest Lewis acid known. Lately, species …

The development of new or more sustainable, active, efficient, controlled, and selective
polymerization reactions or processes continues to be crucial for the synthesis of important …

The chemistry of the p-block elements is a huge playground for fundamental and applied
work. With their bonding from electron deficient to hypercoordinate and formally hypervalent …

This review covers all aspects of 9-borafluorene chemistry, from the first attempted synthesis
in 1960 to the present. This class of molecules consists of a tricyclic system featuring a …

Halogenated triarylboranes (BAr3) have been known for decades, however it has only been
since the surge of interest in main group catalysis that their application as strong Lewis acid …

The synthesis of tris (ortho‐carboranyl) borane (BoCb3), a single site neutral Lewis
superacid, in one pot from commercially available materials is achieved. The high fluoride …
