- Taming the Lewis Superacidity of Non-Planar Boranes: C?H Bond Activation and Non-Classical Binding Modes at Boron
-
The rational design of a geometrically constrained boron Lewis superacid featuring exceptional structure and reactivity is disclosed. It enabled the formation of non-classical electron deficient B?H?B type of bonding, which was supported by spectroscopic and structural parameters as well as computational studies. Taming the pyramidal Lewis acid electrophilicity through weak coordinating anion dissociation enabled a series of highly challenging chemical transformations, such as Csp2?H and Csp3?H activation under a frustrated Lewis pair regime and the cleavage of Csp3?Si bonds. The demonstration of such rich chemical behaviour and flexibility on a single molecular compound makes it a unique mediator of chemical transformations generally restricted to transition metals.

- METHOD FOR PRODUCING TRIS(PERFLUOROALKANESULFONYL)METHIDE ACID SALT
-
There is provided a method for producing a tris(perfluoroalkanesulfonyl)methide acid salt represented by formula [1], including the steps of (a) reacting a methylmagnesium halide represented by formula [2] with a perfluoroalkanesulfonyl fluoride represented by formula [3], thereby obtaining a reaction mixture; and (b) directly reacting the obtained reaction mixture with at least one selected from the group consisting of alkali metal halides, quaternary ammonium salts, and quaternary phosphonium salts. By this method, it is possible to easily produce the target methide acid salt with high yield.
