contribute to the hydrolysis reaction. The sensitivity of the hydrolysis reaction to various structural parameters in the substrates indicates that hydrolysis occurs at the ester rather than the carbamate functionality. In plasma, the rates of hydrolysis correlate with partition coefficients, the most lipophilic compounds being the most stable. An aspirin derivative suffers two consecutive enzymatic reactions

vital role in stabilizing key intermediates in bond‐formation reactions. We report that binuclear benzo[h]quinoline‐ligated NiII complexes, upon oxidation, undergo reductiveelimination to form carbon–halogen bonds. A mixed‐valent Ni(2.5+)–Ni(2.5+) intermediate is isolated. Further oxidation to NiIII, however, is required to trigger reductiveelimination. The binuclear NiIII–NiIII intermediate lacks a
金属-金属键在稳定键形成反应中的关键中间体方面起着至关重要的作用。我们报告说,双核苯并[ h ]喹啉连接的Ni II配合物在氧化时会经历还原消除反应,从而形成碳-卤素键。分离出混合价的Ni(2.5 +)– Ni(2.5+)中间体。但是,需要进一步氧化成Ni III才能引发还原反应。双核的Ni III -Ni III中间缺少镍Ni键。每个Ni III都经过单独但快速的还原消除,从而生成Ni I物种。这些双核Ni络合物的反应性突出了Ni和Pd在介导键形成过程中的根本区别。

clathrate-like hydrates. The results can be summarized as follows: (1) for 14 carboxylates the formation of a clathrate-like hydrate is newly confirmed; (2) judging from melting points and hydration numbers, the hydrates can be classified into three groups: I, II, and III; (3) the group I hydrates, formed by the carboxylates with R=H, CH3, C2H5, n-C3H7, i-C3H7, and t-C4H9, have hydration numbers around

di-p-tolyltelluride with ferric, cupric and mercuric chloride, performed in glacial aceticacid, effects the reduction of the metallic salts giving rise to di-p-tolyltellurium dichloride. In toluene solution only the ferric chloride was reduced and the anhydride of di-p-tolyltellurium hydroxychloride formed, due to the hydrolysis of the tellurium dichloride. The reaction of the mentioned telluride and benzoyl
