Cyclophanes are a venerable class of macrocyclic and cage compounds that often contain unusual conformations, high strain, and unusual properties. However, synthesis of complex, functional derivatives remains difficult due to low functional group tolerance, high dilution, extreme reaction conditions, and sometimes low yields using traditional stepwise synthetic methods. “Design of experiments” (DOE)...
Raus mit dem Alten, rein mit dem Neuen: Kann die Transmetallierung von metall‐organischen supramolekularen Aggregaten zu neuen Strukturtypen führen? Eine Serie von Bi‐, Sb‐ und As‐Cryptanden wird beschrieben, die durch Transmetallierung einen neuartigen P2L3‐Cryptanden ergeben (siehe Schema). Die P‐S‐Bindungen verhalten sich reversibel – so wie klassische Metall‐Ligand‐Bindungen –, woraus sich ein...
