chlorobenzene(cyclopentadienyl)iron(II) hexaflurophosphate undergo nucleophilic substitution with sodium phenoxide to give tricarbonyl(4-chloro-1-phenoxybenzene)chromium(O) and phenoxybenzene(cyclopentadienyl)iron(II) hexaflurophosphate, respectively. In the former case, the second chlorine is subsequently displaced by methoxide, and this represents a potentially versatile synthesis of substituted diphenyl ethers
