Arynes are among the most active organic intermediates and have found numerous
applications in expeditious preparation of substituted arenes. In the past 20 years, chemists …

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 …

Chalcones are aromatic ketones found in nature as the central core of many biological
compounds. They have a wide range of biological activity and are biogenetic precursors of …

Pyridine-and quinoline-stabilized silyl cations have been prepared, and their structure in
condensed phases unambiguously assigned using 1H, 13C, 15N, 29Si, and 1H DOSY NMR …

A new NMR‐based Lewis acidity scale is suggested and its application is demonstrated for
a family of silyl Lewis acids. The reaction of p‐fluorobenzonitrile (FBN) with silyl cations that …

Cyclic silylated chalconium borates 13 [B (C6F5) 4] and 14 [B (C6F5) 4] with peri‐
acenaphthyl and peri‐naphthyl skeletons were synthesized from unsymmetrically …

A norbornene-based sulfide stabilized silylium ion 4 has been synthesized. The S–Si
interaction was studied in solution and in the solid state by NMR spectroscopy and X-ray …

Novel norbornene-based imine-stabilized silylium ions 2 have been synthesized via the
simple reaction of sulfide-stabilized silylium ion 1 with carbonyl derivatives. Those silylium …

Chalcones are aromatic ketones found in nature as the central core of many biological
compounds. They have a wide range of biological activity and are biogenetic precursors of …

L'objectif de cette thèse est l'étude d'une nouvelle famille d'ions silyliums et leur potentiel
pour la catalyse. Ces espèces cationiques possèdent des propriétés remarquables en tant …
