The kinetics of phosphine substitution in CpRu(PPh3)2X (X = Cl, Br, I, N3, and NCO) is consistent with a dissociative mechanism. The complexes react with chloroform to yield CpRu(PPh3)2Cl by a mechanism that involves phosphine loss.

The kinetics of dehydroxylation of crocidolite have been studied in Z)CICUO. The kinetic data may be interpreted in terms of a diffusion-controlled reaction based on radial diffusion out of a cylinder. The activation energy for the process is 49 kcal/mole.
