  A Masked Two-Coordinate Cobalt(I) Complex That Activates C–F Bonds

  摘要：

  We report the isolation, characterization, and reactions of the unsaturated complex (LCo)-Co-tBu (L-tBu = bulky beta-diketiminate ligand). The unusual slipped kappa N,eta(6)-arene binding mode in (LCo)-Co-tBu interconverts rapidly and reversibly with the traditional kappa N-2,N' ligation mode upon binding of Lewis bases, making it a "masked" two-coordinate complex. The mechanism of this isomerization is demonstrated using kinetic studies. (LCo)-Co-tBu is a stable yet reactive synthon for low-coordinate cobalt(I) complexes and is capable of cleaving the C-F bond in fluorobenzene.

  Reported N-2 complexes of cobalt do not have substantial weakening of the N-N bond. Using diketiminate ligands to enforce three-coordinate geometries, we have synthesized several novel CoNNCo complexes. In formally univalent complexes, cobalt is poorer than iron at weakening the N-N bond, but in formally zerovalent complexes, cobalt and iron give similar N-N weakening. The weakening is due to cobalt-to-N-2 pi-backbonding, and potassium cations pull more electron density into N-2. These results show that the low coordination number of a trigonal-ptanar geometry is impetus enough to make even the etectronegative cobalt weaken the N-N bond of N-2.
