acetonitrile gave trans-[Fe(P2N2C2(CH3CN)2](ClO4)2 (VI) and trans-[Fe(P2N2C2H4)(CH3CN)2](ClO4)2 (VII), respectively. Interaction of FeCl2 ∗d 4H2O with one equivalent of N,N′-bis[o-(diphenylphosphino)benzylidene]-1,6-diaminohexane (P2N2C6) in refluxing gave trans-FeCl2(P2N2C6) (VIII). Complexes I–VIII have been fully characterized by analytical and spectroscopic methods. The structure of IV has been established

The reaction of N,N′-bis[o-(diphenylphosphino)benzylidene]-1,2-diaminoethane (L2) with one equivalent of RuCl2(PPh3)3 in dichloromethane at room temperature gave trans-RuCl2(PPh3)(κ3-L2) 2 in high yield. When refluxed in toluene in air, 2 was converted quantitatively to trans-RuCl2(κ4-L2) 3. When treated with one equivalent of hydrogen peroxide in chloroform, 2 was oxidized to trans-RuCl2(PPh3)(κ3-L3) 4, in which the pendant phosphine has been oxidized to a phosphine oxide. Complex 4 can be further
oxidized with another equivalent of hydrogen peroxide to trans-RuCl2(PPh3)(κ3-L4) 5, in which the amino group trans to PPh3 has been oxidized to an imino group. When treated with excess hydrogen peroxide in ethanol, 3 was oxidized to trans-RuCl2(κ4-L5) 6, in which the diamino moiety [–N(H)CH2CH2N(H)–] has been oxidized to a conjugated diimino moiety (–NCHCHN–). The solid-state structures of 2, 4, 5 and 6 were ascertained by X-ray crystallography. Catalytic studies show that 2
is an effective catalyst for the oxidation of alkanes, alkenes and alcohols with air or tert-butyl hydroperoxide. Experimental evidence suggests that free radicals are probably involved in the catalytic oxidation processes.
