Notes:
Oxametallacycles [Fe(C5Me5)(CO){C3(C6H4-o-Cl)(CO2Me)(R)Oa}(Fe-Oa)] (2, R = OMe; 4, R = Me) are accessible from the chelate (chloroaryl)carbene complex [Fe(C5Me5)(CO){C(OMe)C6H4-o-Cla}(Fe-Cla)][OTf] (1) upon treatment with the appropriate carbanions. Their formation arises from the lability of the chlorine atom. The related phosphonium salt [Fe(C5Me5)(CO){C3(C6H4-o-PMe3)(CO2Me)(OMe)Oa}(Fe-Oa)][OTf] (3) is formed only for the bis(ester) derivative, via Ar-Cl bond activation. No reaction occurs for 4, for which the coordination of the acetyl group has been supported by an X-ray analysis.
