Synthesis and Structure of the First Bridgehead Silylium Ion

Year: 2014

Type: article

Abstract: We report the first successful synthesis of the long-sought arene-solvated bridgehead silylium ion [Si 4 Me 3 (CH 2 ) 6 ][CHB 11 Cl 11 ] by hydride abstraction from the tetrasilaadamantyl derivative HSi 4 Me 3 (CH 2 ) 6 with the trityl salt [Ph 3 C][CHB 11 Cl 11 ] in toluene, benzene, or bromobenzene solution. The silylium···arene complex was characterized by X-ray diffraction analysis and by NMR spectroscopy and was studied computationally. NMR studies show that the silylium species undergoes a dynamic solvate exchange in BrPh/MePh mixed solvent.
