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 …

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 …

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 …

Bis (perfluorocatecholato) silane Si (catF) 2 was prepared, and stoichiometric binding to
Lewis bases was demonstrated with fluoride, triethylphosphine oxide, and N, N …

The Lewis acidity of several aryl-substituted tetrylium ions was classified experimentally by
applying the Gutmann–Beckett method and computationally by calculation of fluoride ion …

Strong Lewis acids are essential tools for manifold chemical procedures, but their scalable
deployment is limited by their costs and safety concerns. We report a scalable, convenient …

An automated reaction monitoring system capable of unattended sample aliquoting and
dilution, as well as immediate quantification and identification of reaction components via …

The hydrogen-bonding activation for 66 organocatalysts has been quantified using a 31P
NMR binding experiment with triethylphosphine oxide (TEPO). Diverse structural classes …

The transition metal free catalytic hydroboration of aldehydes and ketones is very limited
and has not been reported with a well-defined silicon (IV) compound. Therefore, we chose to …

Discrete two‐coordinate ZnII organocations of the type (NHC) Zn− R+ are reported, thanks to
NHC stabilization. In preliminary reactivity studies, such entities, which are direct cationic …
