摘要: Avenues to S-based Lewis acids were developed via the oxidation of aryl-sulfoxides with XeF2, giving difluorodiarylsulfoxides which react fluoride abstraction afford acidic fluorosulfoxonium cations; this acidity is derived from S–F σ* orbital and has been probed both experimentally computationally.
