Hierarchical Helicates Bearing Phosphorus‐Based Substituents in the Periphery.

Phosphinate and phosphane substituted hierarchical helicates have been prepared, and the phosphinate derivatives could be characterized in the crystal. The helicate with phosphane substituents was submitted to an orientating study on catalysis, showing its potential to act as chelating ligand for the generation of active rhodium‐based hydrogenation catalysts.
