Chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium is the

organometallic synthetic and catalytic transformations. The compound has idealized Cs symmetry. It is soluble in chloroform, dichloromethane, and acetone
.

Preparation

Chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium was first reported in 1969 when it was prepared by reacting dichlorotris(triphenylphosphine)ruthenium(II) with cyclopentadiene.[1]

RuCl2(PPh3)3 + C5H6 → RuCl(PPh3)3(C5H5) + HCl

It is prepared by heating a mixture of ruthenium(III) chloride, triphenylphosphine, and cyclopentadiene in ethanol.[2]

Reactions

Chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium(II) undergoes a variety of reactions often by involving substitution of the chloride. With phenylacetylene it gives the phenyl vinylidene complex:

(C5H5)(PPh3)2RuCl + HC2Ph + NH4[PF6] → [Ru(C:CHPh)(PPh3)2(C5H5)][PF6] + NH4Cl

Displacement of one PPh3 by carbon monoxide affords a chiral compound.[3]

(C5H5)(PPh3)2RuCl + CO → (C5H5)(PPh3)(CO)RuCl + PPh3

The compound can also be converted into the hydride:[4]

(C5H5)(PPh3)2RuCl + NaOMe → (C5H5)(PPh3)2RuH + NaCl + CH2O
