Abstract
Oxametallacycles [Fe(C5Me5) (CO){C-3(C6H4-o-Cl) (CO2Me)(R)O-a}(Fe-O-a) ] (2, R = OMe; 4, R = Me) are accessible from the chelate (chloroaryl) carbene complex [Fe(C5Me5)(CO){C(OMe)C6H4-o-Cl-a} (Fe-Cl-a)] [OTf] (1) upon treatment with the appropriate carbanions. Their formation arise s from the lability of the chlorine atom. The related phosphonium salt CO){C-3(C6H4-o-PMe3)(CO2Me)(OMe)O-a}(Fe-O-a)][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.
