Iron isopropoxide

Polymer and precursors (FeCl3, iron(III) acetate, titanium isopropoxide, silicon tetraethoxide, and copper(II) chloride) dissolved in organic solvent (acetone, ethyl acetate) and cast onto microscopic slides precursors in situ hydrolyzed... 

The most common hydrox y oxime ligands are salicylaldoximes, complexes of which with copper(II), nickel(II) amd palladium(II), cobalt(II), iron(II), iron(HI) and manganese(II) have been investigated extensively including crystal and molecular structures13 of the first three. In an interesting study,71 the reactions of cobalt bis chelates of this type have been studied with aluminum isopropoxide. 

Diastereoselective epoxidation of an allylic alcohol. Epoxidation of either a cis-or Irons-allylic alcohol substituted in the y-position by an alkoxy function by either m-ehloroperbenzoic acid or r-butyl hydroperoxide/VO(acac), results mainly in the anti-cpoxide (9, 109). Epoxidation of the allylic alcohol 1 with m-chloroperbenzoic acid conforms to this pattern, but epoxidation with f-butylhydroperoxide and VO(acac)2 mediated by titanium (IV) isopropoxide favors formation of the jyn-epoxide by a (actor of 10 1. The methyl group attached to the double bond is necessary for this unusual syn-selectivity when it is lacking, epoxidation with f-butyl hydroperoxide/ Ti(l V) is anti-sclcctivc, but less so than epoxidation with the peracid.1... 

The first report on the coordination polymerisation of epoxide, leading to a stereoregular (isotactic) polymer, concerned the polymerisation of propylene oxide in the presence of a ferric chloride-propylene oxide catalyst the respective patent appeared in 1955 [13]. In this catalyst, which is referred to as the Pruitt Baggett adduct of the general formula Cl(C3H60)vFe(Cl)(0C3H6),CI, two substituents of the alcoholate type formed by the addition of propylene oxide to Fe Cl bonds and one chlorine atom at the iron atom are present [14]. A few years later, various types of catalyst effective for stereoselective polymerisation of propylene oxide were found and developed aluminium isopropoxide-zinc chloride [15], dialkylzinc-water [16], dialkylzinc alcohol [16], trialkylalumi-nium water [17] and trialkylaluminium-water acetylacetone [18] and trialkyla-luminium lanthanide triacetylacetonate H20 [19]. Other important catalysts for the stereoselective polymerisation of propylene oxide, such as bimetallic /1-oxoalkoxides of the [(R0)2A10]2Zn type, were obtained by condensation of zinc acetate with aluminium isopropoxide in a 1 2 molar ratio of reactants [20-22].

Iron-molybdenum-titanium oxides were prepared via the sol-gel method. Either (NH4)6Mo7024 4H20, and ferric nitrate (FeN), Fe(N03)3-9H20, or FeCb and MoOCL were used as precursors together with Ti-isopropoxide. These solids were characterised by chemical analysis and N2 adsorption. The sol-gel samples developed higher surface areas (c.a. 100 m g ), except for the sol-gel solid prepared with Fe and Mo chlorides as precursors, than those prepared by impregnation. 

All the iron [6.5.6]-P-N-N-P hydrogenation catalysts require activation by an external base. The catalytic profile for achiral complex 32 showed that there is an induction period before rapid catalysis takes place for the TH of acetophenone in basic isopropanol. Unexpectedly, reacting 32 with sodium isopropoxide in either benzene or isopropanol yields the pentadentate ferraaziridine complex 39, which was isolated and structurally characterized (Scheme 10).> This unusual complex is diamagnetic, with... 

Iron tiialkoxides are volatile compounds, except the methoxide which decomposed on attempted distillation in vacuo. Thus ethoxide, -propoxide, n-butoxide, isoprop-oxide, and tert-butoxide distilled at 155, 162, 171, 149, and 136°C, respectively under 0.1 mm pressure. The ebuUioscopic and cryoscopic" " molecular weight determinations in benzene indicated aU these normal alkoxides to be trimeric including the methoxide, whereas the isopropoxide and tert-butoxide are dimeric in boiling benzene. ... 

The process of reducing carbonyl compounds (aldehydes or ketones) to alcohols is therefore known as the Meerwein-Ponndorf-Verley reaction. Although alkoxides of a number of metal(loid)s such as sodium, magnesium, titanium, zirconium, iron, boron, aluminium, tin, and antimony have been used for these reactions, those of aluminium are by far preferred, since they tend to give the minimum degree of side reactions. The use of aluminium isopropoxide over other alkoxides was also preferred by Young et al as well as by Adkins and Cox. ... 

Coaxial spinning can also be used to form polymer-particle composite nanofibers as discussed in Chapter 6. Li et al. (2005a), in their research on decorating the interior of hoUow nanofibers with nanoparticles, used this technique very effectively. The core fluid used was a ferrofluid of magnetic iron oxide particles and the shell layer was a mixture of poly(vinyl p5u-olhdone)/ titanium isopropoxide. Extraction of the core phase of the core-shell nanofibers with octane yielded hollow, magnetically susceptible nanofibers, with their interiors decorated with oxide nanoparticles. 

An extensive series of alkene cations 1 (R = Me to //-G14H29) has been prepared and fully characterized by analytical and spectroscopic methods.Some analogous Cp complex cations have also been prepared. Some of the Gp-iron cations have been reacted with the isopropoxide ion to give new ether derivatives GpFe(GO)2 GH2GH[OGH(GH3)2]R (R = Me, Ft, > -Bu, or -Gi3H27).
