Abstract: The present inventions refers a novel trifluoromethyl thianthrenium compound referred to as TT-CF3+X?, a process for preparing the same and the use thereof for trifluoromethylating organic compounds.

Abstract: A wheel unit of a vehicle having a rim on which a tire is mounted, and having a hub which can rotate about an axis of rotation (T), wherein the hub includes a hub body in which a control element that is mounted such that it is displaceable relative to the hub body in the direction of the axis of rotation (T) between a first position and a second position is accommodated. A fluid channel which fluidically connects the tire to a first space formed between the control element and the hub body is configured in the rim. In the first position of the control element, a fluidic connection between the first space and a second space formed between the control element and the rim is interrupted, whereas, in the second position of the control element, a fluidic connection between the first space and the second space is established.

Abstract: A rotation transmission apparatus for transmitting control and/or working pressures to a fluid channel, which is at least regionally configured or accommodated on or in a shaft, in particular a drive shaft, wherein the rotation transmission apparatus includes a stator assembly, which is arranged such that it is stationary relative to a rotational movement of the shaft and has at least one fluid supply/discharge line, wherein the fluid supply/discharge opens into an annular space which surrounds the shaft at least partially and with which the fluid channel of the shaft is fluidically connected via a branch channel, wherein the annular space is associated with sealing elements, which are arranged and configured in the annular space at least partially such that they seal the annular space from the outside atmosphere when a previously defined or definable overpressure is applied in the annular space.
