Transformation between diphosphinoamines and iminobiphosphines: a reversible p-n-p <-> N=P-P rearrangement triggered by protonation/deprotonation

research article

The protonation of diphosphinoamines attached to pyridine at the ortho-position quantitatively affords the corresponding iminobiphosphine isomers. The starting material can be recovered quantitatively by deprotonation with base. The system represents a new type of molecular switch.
