چکیده

Treatment of the complex [(CO)6Fe2EE%{m-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{m-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 H-, Cor Se-NMR spectroscopy. The structure of [(CO)6Fe2Te2{m-(Ph)C CC(OEt)}W(CO)5] has been established crystallographically.

On the mechanism of imine elimination from Fischer tungsten carbene complexes

(Aminoferrocenyl)(ferrocenyl)carbene(pentacarbonyl)tungsten(0) (CO)5W=C(NHFc)Fc (W(CO) 5 ( E -2)) is synthesized by nucleophilic substitution of the ethoxy group of (CO)5W=C(OEt)Fc (M(CO) 5 (1 (Et) )) by ferrocenyl amide Fc-NH(-) (Fc = ferrocenyl). W(CO) 5 ( E -2) thermally and photochemically eliminates bulky E-1,2-diferrocenylimine ( E -3) via a formal 1,2-H shift from the N to the carbene C ...
