    Description / Table of Contents: Zusammenfassung Die Kinetik der Oxidation einiger primärer, sekundärer und tertiärer aliphatischer Amine mit Kupfer(III)-ditellurat wurde in alkalischem Medium untersucht. Die Reaktion war jeweils erster Ordnung bezüglich Substrat und Oxidationsmittel. Die Reaktionsgeschwindigkeit nahm mit zunehmender Ionenstärke ab. Die Reaktivität stieg in der Reihenfolge sekundäre 〉 primäre 〉 tertiäre Amine an. Ein Mechanismus, der die Bildung eines Adduktes zwischen Amin und Kupfer(III)-monotellurat beinhaltet, wird vorgeschlagen. Dieses Addukt dissoziiert in einem langsamen Schritt, gefolgt von schnellen Schritten, in denen die gefundenen Produkte gebildet werden. Die Anwendbarkeit derTaft-Beziehung wurde getestet und unterstützt den vorgeschlagenen Mechanismus.
    Notes: Abstract The kinetics of oxidation of some primary, secondary and tertiary aliphatic amines by ditelluratocuprate(III) was studied in alkaline medium. The order in both substrate and oxidant was found to be unity each. The reaction rate decreased with increase in ionic strength. The order of reactivity of amines was found to be secondary 〉 primary 〉 tertiary. A mechanism was proposed involving an adduct formation between amine and monotelluratocuprate(III), which dissociates further in a slow step followed by fast steps to give required products. TheTaft linear free energy relationship was shown to be applicable which also supports the proposed mechanism.

    Description / Table of Contents: Abstract Кинетика окисления некоторых аминокислот, а именно, глицина, аланина, валина, леуцина, фенил глицина и фенил аланина дипериодатоаргентатом (III) исследована в щелочных средах. Порядок реакции по каждому из компонентов равен единице. Скорость реакции обратнопропорциональна концентрациям OH− и периодата. Продуктами окисления являются аммиак и соответствующие кетокислоты. Присутствие электроно-акцепторных групп при α-углероде повышает скорость окисления; скорость уменьшается с увеличением алкильной цепи. Эти результаты объясняются на основе механизма переноса двух электронов.
    Notes: Abstract Kinetics of oxidation of some amino acids, viz. glycine, alanine, valine, leucine, phenylglycine and phenylalanine by diperiodatoargentate(III) have been investigated in alkaline medium. The order of the reaction is found to be one with respect to each reactant. The reaction rates are inversely dependent on both [OH−] and [periodate]. The oxidation products are found to be ammonia and the corresponding keto acids. The presence of electron-withdrawing groups at the α-carbon increases the rate of oxidation while the rate decreases with increasing alkyl chain length. A two-electron-transfer mechanism is proposed to explain the results.

    Description / Table of Contents: Abstract Кинетика окисления некоторых кетонов дителлуратокупратом(III) исследовалась спектрофтометрически, определяя расход калиевого дителлуратокупрата(III). Реакция протекает по закону первого порядка, как относительно субстрата, так и окислителя. Была найдена корреляция между порядком реактивности и парциаляной скоростью энолизации этих кетонов. Полагая, что в механизме окисления требуется энольная форма кетона на медленной ступени, объясняется наблюдаемый порядок реактивности этих кетонов.
    Notes: Abstract The kinetics of oxidation of some ketones by ditelluratocuprate(III) were followed spectrophotometrically by estimating the disappearence of potassium ditelluratocuprate(III). The reaction follows first order kinetics in both substrates and oxidant. A correlation is found between the order of reactivity and partial rates of enolization of these ketones. By assuming that the mechanism of oxidation involves the enol form of the ketone in a slow step, the observed order of reactivity of these ketones is explained.

Порядокпо окислителю—нулевой, а по субстрату и катализатору—дробный. Скорость реакции уменьшается с увеличением процентности уксусной кислоты, в то время как [H+] практически не оказывает эффекта на скорость. Скорости для различных замещенных халконов (с заместителями в фенильном кольце, присоединенными к находятся в следующем порядке: н-CH3〉м-CH3〉H〉н-Cl〉м-NO2〉н-NO2. Предлагается механизм, согласно которому за образованием циклического эфира между халконом и OsO4 на быстрой ступени следует его разложение, являющееся ступенью, лимитирующей скорость реакции.
    Notes: Abstract Kinetics of OsO4 catalyzed oxidation of chalcones by Ce4+ has been studied in aqueous acetic-sulfuric acid medium in the temperature range 313 to 338 K. The order in [oxidant] is zero while the order with respect to [substrate] and [catalyst] are each fractional. The rate of the reaction decreased with increase in percentage of acetic acid while [H+] had practically no effect on the rate The rates of various substituted chalcones (with substituents in the phenyl. ring attached to the moiety) are in the orderp-CH3〉m-CH3〉H〉p-Cl〉m-Cl〉m-NO2〉p-NO2. A mechanism in which formation of a cyclic ester between chalcone and OsO4 in a fast step followed by its decomposition in a rate-determining step is envisaged.

    Notes: The kinetics of oxidation of glycine, alanine, phenylalanine, serine threonine, aspartic, and glutamic acid by acid permanganate were investigated to elucidate the mechanism of the reactions. The rate law was found to be \documentclass{article}\pagestyle{empty}\begin{document}$$ \frac{{ - d[Mn\left({VII} \right)]}}{{dt}} = k_0 [a\min oacid][Mn\left({VII} \right)] $$\end{document} The reactions were found to be acid catalyzed, and the kinetic data indicate the participation of the water molecules in the rate-determining step as a proton-abstracting agent from the substrate, as per Bunnett's hypothesis. As Ag+ was found to catalyze these reactions, the oxidation of glycine and glutamic acid was studied, and the rate law was found to be \documentclass{article}\pagestyle{empty}\begin{document}$$ \frac{{ - d\ln [Mn\left({VII} \right)]}}{{dt}} = \frac{{Kk_c^{''} [a\min oacid][Ag^ +]}}{{1 + K[a\min oacid] = K[Ag^ +]}}$$\end{document} A probable mechanism consistent with the observed results is discussed.
