Two novel silver complexes with thianthrene (TA) as a ligand have been synthesized in the poorly coordinating solvent liquid sulfur dioxide, using silver salts with weakly coordinating anions [BF4]− and [SbF6]−. Both colorless compounds contain discrete molecular entities and SO2 molecules included in the crystal structure. Selection of crystals and the diffraction data collection were performed at low temperatures (123 K). The tris(μ-thianthrene-κ2S)disilver(I) bis(hexafluoroantimonate) sulfur dioxide solvate [Ag2(TA)3][SbF6]2·5SO2 (1) (monoclinic, P21/c, a = 21.644(3), b = 12.4216(4), c = 21.934(3) Å , β = 115.04(1)°, Z = 4) is made up of complexes bearing three TA units acting as bridging ligands with both S atoms towards two Ag+ ions with d(Ag+-Ag+) = 2.911 Å giving the [Ag2(TA)3]2+ unit approximately D3h molecular symmetry. The bis(μ-thianthrene-κ2S)disilver(I) bis(tetrafluoroborate) sulfur dioxide solvate [Ag2(TA)2][BF4]2・3SO2 (2) (monoclinic, C2/c, a = 21.0045(6), b = 7.4553(2), c = 22.6024(6) A° , β = 109.65(0)°, Z = 4) is made up of [Ag2(TA)2]2+units with two bridging TA units coordinating two Ag+ ions with d(Ag+-Ag+) = 2.925 Å giving the complexes approximately D2h molecular symmetry. Weak, secondary bonds between Ag+ and the F atoms of the anions, such as Ag···F-SbF5 = 2.862(4) Å in 1 or Ag···F-BF3 = 2.773(2) Å in 2, and with O atoms of SO2 molecules link the complexes with the anions and the solvate molecules, respectively.

Weakly Coordinating Anion

Carbocations have played a central role in the chemical sciences for over a century. In a synthetic setting, most methods utilize stabilized tricoordinate carbocations, while there are far fewer examples of reactions featuring nonstabilized dicoordinate cations. Here, we provide an overview of recent developments in the generation of high-energy carbocations mediated by weakly coordinating anions and the C–H insertion reactions of such carbocations. Moreover, we discuss mechanistic studies of these catalytic C–H insertion reactions aimed at furthering our understanding of the reactive nature of these rarely invoked cationic intermediates.1 Introduction2 Background: Phenyl Carbocations3 Silylium/Carborane-Catalyzed C–H Insertion Reactions of Phenyl Carbocations4 Silane-Fueled, Weakly Coordinating Anion-Catalyzed, Reductive C–H Insertion Reactions of Vinyl Carbocations5 C–H Insertion Reactivity of Vinyl Carbocations under Basic Conditions6 Conclusion and Outlook
