Silylated chalconium ions based on peri-naphthalene and acenaphthene scaffolds are synthesized and introduced as versatile amphiphilic reagents. The investigation of their spectroscopic, structural and bonding properties revealed that their silyl Lewis acidity is controlled by the nature of the chalcogen donor and by the carbon backbone. This opens the perspective for an effective fine tuning and control of their reactivity. Their use as amphiphilic CATalyst was exemplarily demonstrated in hydrodefluorination reactions.
