... The toxicity of EBK appears to involve the metabolism of EBK to two neurotoxic gamma-diketones, 2,5-heptanedione and 2,5-hexanedione. Combined EBK/MEK exposure modestly increased gamma-diketone levels in the serum and urine suggesting that MEK potentiates EBK neurotoxicity by stimulating the metabolism of EBK to neurotoxic metabolites. ...
Ethyl n-Butyl ketone (EnBK) may be metabolized by rats to 2,5-heptanedione, which, like its six-carbon counterpart, 2,5-hexanedione, has been shown to be neurotoxic. However, repeated inhalation exposures to high concentrations of EnBK failed to produce serum levels of 2,5-heptanedione high enough to produce neuropathy in rats.
Urinary metabolites of n-heptane following exposure to n-heptane or to technical heptane were identifiable in male Sprague Dawley rats ... Rats were exposed to 1,800 ppm n-heptane for 6 hr. Urine and feces were collected for 24 hr after treatment. ... In rats, 2-heptanol and 3-heptanol were the main biotransformation products of the solvent. 2-Heptanone, 3-heptanone, 4-heptanol, 2,5-heptanedione, valerolactone, 2-ethyl-5-methyl-2,3-dihydrofuran, and 2,6-dimethyl-2,5-dihydropyran were also found as metabolites of n-heptane. ...

A dicationic dichloro-bipyridine-ruthenium complex shows very high catalytic activity in redox isomerization of allylic alcohols but a relatively low one in transferhydrogenation of ketones; surprisingly, the analogous dimethyl-bipyridine-ruthenium complex shows reverse catalytic activities in the two reactions.

A series of ketones and aldehydes are reduced in toluene under H2 in the presence of 5 mol % B(C6F5)3 and either cyclodextrin or molecular sieves affording a facile metal‐free protocol for reduction to alcohols. Similar treatment of arylketones resulted in metal‐free deoxygenation yielding aromatic hydrocarbons.
在H 2下,在5 mol%B(C 6 F 5)3的存在下,一系列甲苯中的酮和醛被还原,环糊精或分子筛提供了一种简便的无金属还原醇的方案。芳基酮的类似处理导致无金属脱氧,生成芳烃。
Directingstrategy has been extensively exploited to maintain activity and selectivity for the rapid access to functionalized molecules and pharmaceutical targets. However, ‘one‐to‐one’ activation model was usually achieved through traditional directingstrategy. Herein, we achieved ‘one‐to‐two’ activation model by slight modification of simple and practical ketoxime and amide functionality. With judicious
