[Cp(2)ZrHCl](n) was found to be a useful reagent for a number of eithe
r ring formation or ring opening reactions involving unsaturated phosp
horus compounds. Furthermore, treatment of a variety of phosphorus der
ivatives with [Cp(2)ZrHCl](n) allowed the preparation of several linea
r or cyclic mono-, di-, tri- or polyphosphanes as well as optically ac
tive diphosphanes.
