P's in a pod: White phosphorus reacts with [M(dppm)2]OTf (M=Rh, Ir; dppm=PPh2CH2PPh2) to give [M(dppm)(Ph2PCH2PPh2PPPP)]OTf whereby a trihapto "P5" ligand is assembled through P=P bond formation between one dppm PPh2 group and an activated P4 molecule (see scheme; P green, M red, C white, phenyl groups omitted). A bimetallic reaction pathway leading to the final product is proposed, as based on in situ 31P NMR studies.(Abstract present only on the URL page and not on the pdf version)
