摘要
Nitrido complexes N Mo(OC(CF3)(2)Me)(3) (1) and N Mo(OC(CF3)(3))(3)(NCMe) (2) containing fluorinated alkoxide ancillary ligands are synthesized in 57% and 50% yield, respectively. Both complexes undergo N-atom exchange within hours at 30 degrees C with acetonitrile and benzonitrile in either THF-d(8) or CD2Cl2, as shown by N-15 NMR studies using labeled (NCMe)-N-15. In both solvents, 2 is the more active in this process. Additionally, both compounds are substantially more active in THF-d(8) than in CD2Cl2. Complex 2 crystallizes in the space group P2(1)/c, adopting a pseudo-square-pyramidal structure in which the nitrido moiety occupies the apical position, 1.633(3) angstrom away from Mo.
