资源简介：
Herein we demonstrate both the importance of Fe(I) in
Negishi cross-coupling
reactions with arylzinc reagents and the isolation of catalytically
competent Fe(I) intermediates. These complexes, [FeX(dpbz)2] [X = 4-tolyl (7), Cl (8a), Br (8b); dpbz = 1,2-bis(diphenylphosphino)benzene], were characterized
by crystallography and tested for activity in representative reactions.
The complexes are low-spin with no significant spin density on the
ligands. While complex 8b shows performance consistent
with an on-cycle intermediate, it seems that 7 is an
off-cycle species.
