Mechanism Of The Reaction

Benzofurazan oxides are formed in excellent yield when certain substituted-2-nitroanilines react with iodosobenzene diacetate in benzene containing 1 per cent. (by volume) of acetic acid. The kinetics of this reaction have been studied. It is considered that the mechanism of the reaction involves a reversible reaction of the 2-nitroaniline with iodosobenzene diacetate to form acetic acid and an intermediate which is then converted to benzofurazan oxide, iodobenzene, and acetic acid. This reaction is therefore similar to the reaction of iodosobenzene diacetate with glycols. The rates of oxidation of substituted-2-nitroanilines could not be correlated with the electrical effect of the substituent. The reasons for this are discussed in detail.

Mechanism Of The Reaction

Oxidation of a mixture of ferrocene and phenylhydrazine with silver oxide in acetic acid affords phenylferrocene and 1,l'-diphenylferrocene. The reaction may also be conducted in acetone or benzene solvent, and benzoquinone may be used as the oxidizing agent. Similar transformations have been observed using p-methoxyphenyl-, p-chlorophenyl-, p-nitrophenyl-, 2,4-dinitrophenyl-, α-naphthyl-, benzyl-, methyl-, and benzoyl-hydrazine, but the reaction failed with acetylhydrazine. The mechanism of the reaction appears to involve free-radical substitution of ferricinium ion.

A novel one-pot method was developed for the synthesis of the title compounds starting from 4-chloro-1-aryl-1-butanones 1, phosphorus trichloride and acetic acid. The end products 2 were obtained in 20–94% yield. The cyclization step under acidic conditions probably occurs as a result of anchimeric assistance of the phosphonic acid group.

Mechanism Of The Reaction

The kinetics of interaction of hematoporphyrin IX with Cu(II) has been studied in an acetic acid – water solvent (50%–50% v/v). The reaction is of first order with respect to the porphyrin whereas the order with respect to copper(II) perchlorate is smaller than one. This is explained by taking into account the interaction between Cu2+ and acetic acid. The reactive species are Cu2+, CuOAc+, and free porphyrin. The mechanism of the reaction is compared to those proposed for similar systems.

Mechanism Of The Reaction

The constant increase in the CO2 concentration in the atmosphere requires us to look for opportunities to convert CO2 into more valuable compounds. In this review, the activity and selectivity of different supported metal catalysts were compared in the hydrogenation of carbon dioxide, and found that Rh is one of the best samples. The possibility of the CO2 dissociation on clean metal and on supported Rh was discussed separately. The hydrogenation of CO2 produces mainly CH4 and CO, but the selectivity of the reaction is affected by the support, in some cases the reduction of the support, the particle size of Rh, and the different additives. At higher pressure methanol, ethanol, and acetic acid could be also formed. The activity of the various supported Rh catalysts was compared and the results obtained for TiO2-, SiO2-, and Al2O3-supported catalysts were discussed in a separate chapter. The compounds formed on the surface of the catalysts during the reaction are shown in detail; mostly, different CO species, adsorbed formate groups, and different carbonates were detected. In a separate chapter the mechanism of the reaction was also discussed.

Mechanism Of The Reaction

Evidence is presented which indicates that a mixture of hydriodic acid, acetic acid and air achieves the oxidation of formylporphyrins through the agency of peroxyacetic acid. The mechanism of the reaction is discussed. The oxidation of Spirographis porphyrin and its isomer are described and the product of these oxidations related to a methoxycarbonyldeuteroporphyrin of known structure. Improvements are recorded for the synthesis of Spirographis porphyrin and related compounds.
