A General Approach for the Synthesis of Arylxenonium(II) Tetrafluoroborates.

ABSTRACT: Arylxenonium(II) salts are the most numerous group of organoxenon compounds, i.e., those containing Xe-C bonds, and must be prepared by different routes that lack universality. Here, we present a general synthetic approach to arylxenonium(II) tetrafluoroborates [RXe][BF₄] containing different degrees of fluorination at the aryl group R via processes that do not require the use of reactive gases or special equipment. The new synthetic access relies on the generation of aryldifluoroboranes RBF₂ in dichloromethane solution by means of the reaction of K[RBF₃] and BF₃·OEt₂, which are then transformed in a subsequent step to [RXe][BF₄] salts. This route is not only more accessible than previously existing methods but also yields a
