摘要：Three novel η3-2-azaallyl iron(I) complexes, [(2-PPh2)C6H4](CH=N-CH)C6H4(4-R)]Fe(PMe3)2(4 - 6) (R = H (4), Cl (5) and OMe (6)), were prepared through the reactions of Schiff base preligands [(2-PPh2)C6H4](CH=NCH2)C6H4(4-R)] (1 - 3) (R = H (1), Cl (2) and OMe (3)) with Fe(PMe3)4via sp3C-H bond activation under mild reaction conditions. Compared with the reported 2-azaallyl cobalt complexes, these are the first 2-azaallyl iron(I) complexes obtained via Csp3-H bond activation. Complex [(2-PPh2)C6H4](CH=N-CH) (C6H4)FeBr(PMe3)2(7) was obtained through the reaction of 4 with EtBr. The ligand replacement reaction of complex 4 with CO delivered the dicarbonyl iron(I) complex [(2-PPh2)C6H4](CH-N=CH) (C6H5)Fe(CO)2(PMe3) (8). The molecular structures of complexes 4 and 6 were determined by single crystal X-ray diffraction.
