DOIAbstract
Treatment of the complex [(CO)6Fe2EE'{μ-C(Ph)=C-C(OEt)=M(CO)5}], (1: E=S, E'=Se; M=Cr; 2: E=S, E'=Se; M=W; 3: E=E'=Te; M=Cr and 4: E=E'=Te; M=W), with excess Bu3SnH in hexane at 0°C produces enol ether derivatives: (CO)6Fe2{μ-EC(Ph)(H)-C(E')=C(H)(OEt)} (E/Z-5: E=S, E'=Se and E/Z-6: E=E'=Te). All the compounds have been characterised by IR and 1H-, 13C- or 77Se-NMR spectroscopy. The structure of [(CO)6Fe2Te2{μ-(Ph)C=CC(OEt)}W(CO)5] has been established crystallographically
