Ferric oxide unites with many bases to form ferrites, to which the general formula M20.Fe203, or MFe02, is given. The free acid HFe02 possesses the same empirical formula as the monohydrate of feme oxide, Fe203.H20.

Our spectral and kinetic characterization of the oxidized intermediates of MnP compound I (MnPI), and MnP compound II (MnPII) indicate (Fig. 1) that the oxidation states and catalytic cycle of MnP are similar to LiP and HRP (6,15,16,19). MnPl contains two oxidizing equivalents over the native feme enzyme. The first equivalent resides in the Fe =0... 

SALTS OF IKON.—It has been shown that iron is susceptible of two definite degrees of oxidisation, forming a protoxide—FeO—and a sesquioxlde — Fea Oa. Both those oxides are salifiable, giving rise to ferrous and feme Baits. The most important is the native protocarbonate, which constitutes the principal source of British iron, and has, therefore, been fully described in treating of the ores of this metal. 

In small-scale syntheses, a wide variety of oxidants has been employed in the preparation of quinones from phenols. Of these reagents, chromic acid, feme ion. and silver oxide show outstanding usefulness in the oxidation of hydroquinones. ThaUium(lll) trifluoroacetate converts 4-halo-or 4-fOT-butylphenols to 1,4-benzuquinones in high yield. For example, 2 bromo-3-methyl-5-r-butyl 1,4-benzoquinone (4) has been made by this route. 

According to T. Curtius, feme chloride is reduced by hydrazine to ferrous chloride a reaction investigated by E. Miiller and G. Wegdin, and F. Schrader. E. J. Cuy found that in the reaction between hydrazine and a ferric salt in acid soln., one mol of hydrazine requires between one and two eq. of ferric salt for oxidation. The limiting reaction may be expressed as follows N2H 5-)-Fe" =NH 4+JN2+H +Fe". A. W. Browne and F. F. Shetterly showed that ferric oxide and hydrazine in aq. soln, yield ammonia, but no hydrazoic acid, while nickel sesquioxide and cobalt sesquioxide yield ammonia and traces of hydrazoic acid. H. Franzen and 0. von Mayer made complex cobalt salts—e.g. CoC12(N2H4)2, etc.—with hydrazine in place of ammonia. T. Curtius found that platinum is precipitated when a soln. of hydrazine is added to a neutral soln. of platinum...

Redox-catalyzed migratory insertion of CO into [FeMe(COXPPh3)Cp] rapidly gives a high yield of [Fe(COMeXCOXPPh3)Cp] (531). Synthesis of formic acid esters via oxidation of [FeH(CO)2Cpj by cerium(IV) or copper(II) in alcohols, ROH, also proceeds via initial one-electron oxidation the paramagnetic formyl [Fe(CHOXCO)(ROH)Cp]+ is implicated as an intermediate (532)2 (Section VII,E).
