3a,6a‐Diaza‐1,4‐diphosphapentalene (DDP) reacts with halocarbons to give addition products to one or both phosphorus atoms depending on the substrate. Chlorotriphenylmethane affords a 1,4‐addition product, which slowly decomposes in solution to form the Ph 3 C radical and the chloro‐DDP coupling product with a P–P bond. Benzyl chloride is added to one phosphorus atom to form hypervalent (trivalent, four‐coordinate) phosphorus with a N ··· P distance (nonvalent interaction) of 2.191(2) Å. A workup of the latter with GeCl 2 results in a complex salt containing the GeCl 3 – anion and cation with covalent N–P bonding.
