  Treatment of cis-(Me3P)(4)FeMe2 with two equiv (neo)PeN=CH(2-py) afforded kappa-N,N'-(neo)PeN=CH(2-pyridy1))(2)FeMe2 (2-P). Reductions of FeCl2 with Na/Hg in the presence of (neo)PeN=CH(2-pyridyl) or (neo)HexN=CH(2-pyridyl) and L (H2C=CHCO2Me, PhCCPh, PMe3) gave tentative evidence of [kappa-N,N'-(neo)PeN=CH(2-pyridy1)}(2)Fe(H2C=CHCO2Me) (2-P), but (x-N,N'-(neo)PeN=CH(2-pyridyI)}(2)Fe(PhCCPh) (5-P), (kappa-N,N'-neoHexN=CH(2-pyridy1)}(2)Fe(PhCCPh) (5-H), and kappa-N,N'-(neo)HexN=CH(2-pyridy1))(2-)Fe(PMe)}(2-) (6-H) were all isolated in good yield. Phosphine complex 6-H could be alkylated with CH3I or CH3OTf to afford kappa-N,N'-(neo)HexN=CH(2-pyridyl)}(2-)Fe(PMe3)Me]I-+(-) (7-H-I) or kappa-N,N'-(neo)HexN=CH(2-pyridyl)}(2-)Fe(PMe3)Me]I-+(-) OTf- (7-H-OTf) center dot [kappa-N,N'-RN=CH(2-pyridyl)}(3-)Fe][OTf](2) (R = (neo)Pe, 8-P-OTf; (neo-)Hex, 8-H-OTf) omplexes were also prepared from Fe(OTO)(2) in order to identify potential byproducts in certain reactions. Compounds 2-P and 7-H-0Tf were tested for ethylene oligomerization activity, to no avail. Complexes 2-P, 5-H, 6-H, and 7-H-OTf were structurally characterized and evaluated by Mossbauer spectroscopy, and 5-H was shown to possess a redox non-innocent alkyne ligand, while the alpha-alkyliminopyridine ligands of 6-H were classified as radical anions, rendering all compounds describable as Fe(ll).
