CycloN2P2‐Phos! The use of the multidentate phosphine, CycloN2P2‐Phos (see graphic), which contains four heteroatoms (two nitrogen and two phosphorus atoms), in the palladium‐catalyzed asymmetric allylic etherification (AAE) of alcohols and silanols leads to excellent levels of enantioselectivity (up to 99 % ee).
