A series of complexes of transition metal ions (Cr3+, Mn 2+, Co2+, Ni2+, Cu2+, Zn 2+) and of lanthanide ions (La3+, Nd3+, Gd 3+, Dy3+, Lu3+) with the anions of ferrocenylmethyl-L-cysteine [(C5H5)Fe(C5H 4CH(R)SCH2CH(NH3+)CO 2-] (L1) and with the dianions of 1,1?-ferrocenylbis(methyl-L-cysteine) [Fe(C5H 4CH(R)SCH2CH(NH3+) CO 2-)2] (R = H, Me, Ph) (L2) as N,O,S-donors were prepared. With the monocysteine ferrocene derivative L 1 as ligands complexes [MIIL12] or [CrIIIL12]Cl type complexes are formed whereas the bis(cysteine) ligand L2 yields insoluble complexes of type [ML2]n, presumably as coordination polymers. The magnetic moments of [MnIIL2]n, [PrIIIL 2]n(OH)n and [DyIIIL 2]n(OH)n exhibit “normal” paramagnetism.

Introducing a new discovery about 12180-80-2, Name is 1,1′-Dibenzoylferrocene

1,1′-Dibenzoylferrocene reacts with tetraphosphorus decasulphide to yield, in addition to the expected 1,1′-bis(thiobenzoyl)ferrocene, a minor, yellow by-product (1) of composition C24H18FeS3.Crystals of (1) are monoclinic, space group P21/n with a = 11.769(3), b = 11.750(4), c = 14.835(2) Angstroem, beta = 98.63(1) deg, and Z = 4; the structure was refined from diffractometer data to an R value of 0.041.The structure was found to be that of 1,4-diphenyl-1,4-epithio-2,3-dithia<4>(1,1′)ferrocenophane, in which the two rings of the ferrocene nucleus are spanned by a 1,2,4-trithiolane ring.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 12180-80-2, and how the biochemistry of the body works.Application In Synthesis of 1,1′-Dibenzoylferrocene

Introducing a new discovery about 12180-80-2, Name is 1,1′-Dibenzoylferrocene

Ferrocenes bearing acyl substituents in the cyclopentadienyl rings [Fe(eta5-C5H4COR)(eta5-C 5H5)] and [Fe(eta5-C5H 4COR)2] (R = CH3, CF3 and Ph) were examined as new driers for solvent-borne alkyd binder. All studied ferrocenes were found to be active catalysts for cross-linking reaction of the alkyd. These iron(II) compounds give solid polymeric films with hardness and drying time comparable to the commercial cobalt(II) drier. Acetyl- and benzoyl-substituted ferrocenes show an excellent synergic effect with the cobalt drier giving hard polymeric films within short drying time. The kinetics of the alkyd autoxidation was followed by FTIR spectroscopy. Spin-trapping ESR technique has proven the important role of the ferrocenium cation upon decomposition of hydroperoxides by ferrocene-based driers. The peroxy and alkoxy radicals, appearing in drying process, were resolved by the new spin trap methyl-N-mesityl nitrone.

The application of a dendrimer in a redox-switchable catalytic process is reported. A monomeric and the corresponding dendritic ferrocenylphosphane ligand were used to develop well-defined controllable catalysts with distinct redox states. The corresponding ruthenium(II) complexes catalyze the isomerization of the allylic alcohol 1-octen-3-ol. By adding a chemical oxidant or reductant, it was possible to reversibly switch the catalytic activity of the complexes. On oxidation, the ferrocenium moiety withdraws electron density from the phosphane, thereby lowering its basicity. The resulting electron-poor ruthenium center shows much lower activity for the redox isomerization and the reaction rate is markedly reduced.

We report that Mn(IV)-oxo porphyrin complexes, MnIV(O)(TMP) (1) and MnIV(O)(TDCPP) (2), are capable of activating the C-H bonds of hydrocarbons, including unactivated alkanes such as cyclohexane, via an oxygen non-rebound mechanism. Interestingly, 1 with an electron-rich porphyrin is more reactive than 2 with an electron-deficient porphyrin at a high temperature (e.g., 0 C). However, at a low temperature (e.g., -40 C), the reactivity of 1 and 2 is reversed, showing that 2 is more reactive than 1. To the best of our knowledge, the present study reports the first example of highly reactive Mn(IV)-oxo porphyrins and their temperature-dependent reactivity in C-H bond activation reactions.
