The reaction of tricarbonyl-<η⁶-3-(o-methyl- or o-methoxyphenyl)-1-phenylprop-2-en-1-one>chromium with nonacarbonyldi-iron gives specifically one diastereoisomer of the η⁴-Fe(CO)3-α,β-unsaturated ketone-η⁶ Cr(CO)3-ortho-substituted arene complex, the relative configuration (RS,SR) of which was unambiguously established by X-ray analysis; the equivalent reaction using the 3-m-methoxyphenylpropenone isomer gives a 1 : 1 mixture of two diastereoisomers.
