CH 2 CN bridging ligands are novel . Treatment of acetonitrile with the alkyl lanthanum or cerium compounds 1 results not in the expected insertion of a nitrile group into the Ln‐C σ bond, but rather in activation of a CH bond in the methyl group, leading to the new type of complex 2 . In the case of the dimeric lanthanum complex 2 , where n = 2, the product has been shown to contain an eight‐membered ring in a chair conformation (Cp * C 5 Me 5 ).
