✦ Synopsis


The nucleophilic aromatic substitution of halogen in metal arene p-complexes h 6 -(ArF)Cr(CO) 3 and [h 6 -(ArHal)FeCp] + [PF 6 ] -(Hal=F,Cl) with phosphoryl-stabilized carbanions ZCH 2 P(O)(OEt) 2 (Z=COOEt, CN) allows the synthesis of metal p-complexes of a-EWG-substituted arylmethylphosphonates in high yields.
