Diisopropylbenzene occurs in three isomeric forms, namely as the ortho, the meta, and the para derivatives ... . Orally, they are of very low toxicity. Of 10 rats dosed with 5.0 ml/kg, no deaths for the meta, and one death for the ortho and the para isomers occurred. Russian reports of 1970 indicate that rats and rabbits exposed to 0.2 to 1.0 mg/liter (30 to 150 ppm) for 90 minutes daily for 5 weeks developed vascular hyperemia, hemorrhaging in most major organs, and fatty and protein dystrophy in the liver, kidney, and heart, and hyperplasia of the bone marrow. meta-Diisopropylbenzene caused decreased fertility in the rat and mouse at 1 to 3 mg/liter for 30 days.

equipment. In this report, photo-induced deep aerobic oxidation of (poly)alkyl benzene to benzene (poly)carboxylic acids was developed. CeCl3 was proved to be an efficient HAT (hydrogen atom transfer) catalyst in the presence of alcohol as both hydrogen and electron shuttle. Dioxygen (O2) was found as a sole terminal oxidant. In most cases, pure products were easily isolated by simple filtration, implying
氧化是自然界和化学工业中生产含氧化学品的主要化学过程。目前,苯甲酸和苯多羧酸(BPCAs)的工业生产主要以聚烷基苯的深度氧化为主,由于形成消耗臭氧层的溴化溴和对生产设备的腐蚀危害,在环境和经济上都有些不利。 . 在这份报告中,开发了(多)烷基苯的光诱导深度有氧氧化为苯(多)羧酸。CeCl 3被证明是在醇存在下作为氢和电子穿梭的有效HAT(氢原子转移)催化剂。双氧 (O 2) 被发现是唯一的终端氧化剂。在大多数情况下,纯产品很容易通过简单的过滤分离,这意味着大规模实施的优势。该反应提供了从天然丰富的石油原料中生产有价值的精细化学品的理想方案。

intermediates play a major role and are generated by hydrogen-atom abstraction from substrate C-H bonds or initial nitrene-addition to one of the olefinic carbons. Subsequent processes include solvent-caged radical recombination to afford the major amination and aziridination products but also one-electron oxidation of diffusively free carboradicals to generate amidination products due to carbocation

as a "one-radical" initiator of styrene polymerization. The ABNO-trapped cumyl radical 29 is a particularly stable trialkylhydroxylamine, whose thermolysis half-life is 2.1 h at 150 degrees C. Taking advantage of this stability, we trapped the cumyl radical centers from 7 to afford tris adduct 32a. While the behavior of the meta bisazoalkane 6 can be mostly predicted from that of 4, the para isomer

(sp3)C–C(sp3) and (sp3)C–H bonds in aryl alkanes by the use of NaNO2/HCl was explored. The method is chemical-oxidant-free, transition-metal-free, uses water as the solvent, and proceeds under mild conditions, making it valuable and attractive to syntheticorganicchemistry.

enabled arene C-H trifluoromethylation with the Langlois reagent CF3SO2Na under mild reaction conditions. The merger of electrosynthesis and photoredox catalysis provided a chemical oxidant-free approach for the generation of the CF3 radical. The electrophotochemistry was carried out in an operationally simple manner, setting the stage for challenging C-H trifluoromethylations of unactivated arenes
