Abstract

A zwitterionic construction has been synthesized that covalently links a trialkylsilylium cation and a weakly coordinating carborane anion in one neutral molecule (see X-ray structure; Si green, C gray, B orange, Cl red). The silylium character of this molecule is supported by DFT calculations (see LUMO), ²⁹Si CP/MAS NMR spectroscopy, and reactivity.
