Abstract

Sterically hindered pentacoordinate tert-butylsiliconium halide complexes undergo methyl halide elimination. The products have one covalent and one dative N-Si bond, both in the unprecedented equatorial position. A complete pseudorotation coordinate is demonstrated with suitable crystal structures.
