The diphosphine (Me2N)2PCH2P(NMe2)2 reacts with the tetraamino macrocycle cyclen at about 100°C in a closed system via cleavage of the P-C bond to yield cyclenphosphorane and bis(dimethylamino)methylphosphine. The presence of dimethylamine in this reaction is necessary, since a similar reaction which allows the amine to escape, produces an oligomeric product of formula [(C8H16N4)PCH2P]n.
