Beschreibungen/Notizen

• We have prepared [2]rotaxanes, the behavior of which as switchable catalysts depends on their pirouetting motion, which can be controlled through the addition and removal of Na+ ions. At least three sequential on/off cycles of a Michael reaction can be performed in situ when using the NaTFPB/[2.2.2]cryptand reagent pair to switch “on” and “off” the catalytic ability of the [2]rotaxanes. Two‐way street: The catalytic activity of the [2]rotaxane catalysts can be switched between “on” and “off” states over at least three different cycles through in situ addition and removal of Na+ ions.
