Condensation of the iron complex with cyclopentanone in perchloric acid-acetic anhydride-ether medium had been attempted. The non-crystalline residue, after methanol washing and drying in air for several weeks, exploded on being disturbed. This was attributed to possible presence of a derivative of ferrocenium perchlorate, a powerful explosive and detonator. However, methyl or ethyl perchlorates alternatively may have been involved. 

We have delineated viable coordinated ligand reactions and their attendant intermediates for the stoichiometric conversion of CO ligands selectively to the C2 organics ethane, ethylene, methyl (or ethyl) acetate, and acetaldehyde. We now outline results from three lines of research (1) T -Alkoxymethyl iron complexes CpFe(C0)2CH20R (2) are available by reducing coordinated CO on CpFe(C0)3+ (1) [Cp = r -CsHs]. Compounds 2 then form t -alkoxyacetyl complexes via migratory-insertion (i,e. CO... 

Acetic acid is formed when methane reacts with CO or C02 in aqueous solution in the presence of 02 or H202 catalyzed by vanadium complexes.327 A Rh-based FeP04 catalyst applied in a fixed-bed reactor operating at atmospheric pressure at 300-400° C was effective in producing methyl acetate in the presence of nitrous oxide.328 The high dispersion of Rh at sites surrounded by iron sites was suggested to be a key factor for the carbonylation reaction. 

The synthesis of this special type of metallo-silanol starts most efficiently with an appropriate silyl metal complex, such as Cp(OC)2Fe-SiMe2R (R = H, OMe). An anionic shift of the silyl group from the iron to the cyclopentadienyl unit can be induced with lithium diisopropylamide, leading to the metallates 21a,b. Methylation with methyl iodide produces the neutral methyl iron complexes (C5H4SiMe2R)(OC)2Fe-Me (R = H, OMe), which can be converted either, for R = H, by the Co2(CO)8 method, or, for R = OMe, by hydrolysis in the presence of acetic acid, into the corresponding silanol 22.

A solution of -butyllithium (19.57 mL, 2.5 M in tetrahydrofuran, 48.9 mmol) is added at 0 °C to a solution of diisopropylamine (6.85 mL, 48.9 mmol) in tetrahydrofuran (100 mL). After 10 min, the reaction is cooled to -78 °C followed by dropwise addition of tricarbonyl(methyl 3,5-hexadienoate)iron (12.39 g, 46.6 mmol) in tetrahydrofuran (5 mL). The reaction mixture is kept at this temperature for 20 min. After the addition of methyl iodide (10 mL, 22.7 g, 159.9 mmol), the mixture is allowed to warm to room temperature over 1 h and quenched with a saturated solution of ammonium chloride. The aqueous layer is extracted with ethyl acetate (3 x 50 mL). The combined organic layers are washed with 1 N phosphoric acid (2 x 40 mL) and saturated aqueous sodium hydrogen carbonate (1 X 40 mL), then dried with magnesium sulfate and concentrated. The resulting oil is purified by chromatography (hexane/ethyl acetate, 19 1) to afford the a-methylated (r -diene)iron complex as a yellow solid mp 43-44 °C Rf = 0.53 (hexane/ethyl acetate, 9 1) dr 94 4 9.46 g (72%). ... 

In the early work on the thermolysis of metal complexes for the synthesis of metal nanoparticles, the precursor carbonyl complex of transition metals, e.g., Co2(CO)8, in organic solvent functions as a metal source of nanoparticles and thermally decomposes in the presence of various polymers to afford polymer-protected metal nanoparticles under relatively mild conditions [1-3]. Particle sizes depend on the kind of polymers, ranging from 5 to >100 nm. The particle size distribution sometimes became wide. Other cobalt, iron [4], nickel [5], rhodium, iridium, rutheniuim, osmium, palladium, and platinum nanoparticles stabilized by polymers have been prepared by similar thermolysis procedures. Besides carbonyl complexes, palladium acetate, palladium acetylacetonate, and platinum acetylac-etonate were also used as a precursor complex in organic solvents like methyl-wo-butylketone [6-9]. These results proposed facile preparative method of metal nanoparticles. However, it may be considered that the size-regulated preparation of metal nanoparticles by thermolysis procedure should be conducted under the limited condition. 

Castro (1964) reported that iron(II) porphyrins in dilute aqueous solution was rapidly oxidized by DDT to form the corresponding iron(III) chloride complex (hematin) and DDE, respectively. Incubation of /5,//-DDT with hematin and ammonia gave p./Z-DDD, p./Z-DDE, bis(/5-chloro-phenyl)acetonitrile, l-chloro-2,2-bis(jD-chlorophenyl)ethylene, 4,4 -dichlorobenzophenone, and the methyl ester of bis (jo-chlorophenyl) acetic acid (Quirke et al., 1979). 

Methylcryptaustoline iodide (14) was synthesized from phenylacetic acid 47 by Elliott (39) as shown in Scheme 7. Nitration of 47 to the 6-nitro compound 48 and reduction with sodium borohydride afforded lactone 49. Reduction of the aromatic nitro group with iron powder in acetic acid gave ami-nolactone 50, which was converted to tetracyclic lactam 51 with trifluoroacetic acid in dichloromethane. Reduction of the lactam by a borane-THF complex followed by treatment with methyl iodide afforded ( )-0-methylcryptaustoline iodide (14). 

Reduction of the complex on Raney nickel yielded benzylamine, N-methyl-benzylamine, and N,N-dimethylbenzylamine but no / -phenylbenzylamine, a reduction product resulting under the same reaction conditions from benzyl cyanide. Hydrolysis with dilute sulfuric acid in acetic acid yielded benzylamine only, and oxidation of the complex with potassium permanganate gave 4.2 moles of benzoic acid per mole of complex. The bromide anion can be exchanged metathetically with various other anions such as perchlorate, iodide, and thiocyanate. When heated at 100° C. in vacuum, the complex lost one mole of benzyl bromide and yielded only one dicyanotetrakis(benzylisonitrile)iron(II) complex.
