The addition of (trimethylsilyl)-diazomethane and its conjugate base to iron beta-diketiminate precursors gives novel dinuclear complexes in which the bridges are either diazomethane derivatives or an alkylidene. One product is an unusual bridging alkylidene complex containing two three-coordinate iron(II) centers. On the other hand, syntheses using the deprotonated diazomethane give two bridging diazomethyl species with binding modes that have not been observed in iron complexes previously. In the presence of a coordinating tetrahydrofuran solvent, a diiron(II) compound with mu-N bridges rearranges to a more stable isomer with mu-N,C bridges, a process that is accompanied by a 1,3-shift of a silyl group.
