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. ... Rats and rabbits exposed to 0.2 to 1.0 mg/l (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/l for 30 days.

Scaled-up sodium-free Birchreductions The so-called Birchreduction is frequently used by chemists despite its daunting conditions: Pyrophoric sodium is dissolved in pure liquified ammonia to achieve partial reduction of aromatics. Peters et al. surveyed and then optimized small-scale electrochemical alternatives to devise a safer protocol that can work on a larger scale with a broad range of functionally

The synthesis of aryl amines via the formation of a C−N bond is an essential tool for the preparation of functional materials, active pharmaceutical ingredients and bioactive products. Usually, this chemical connection is only possible by transition metal-catalyzed reactions, photochemistry or electrochemistry. Here, we report a metal-free arene C−H amination using hydroxylamine derivatives under benign
Syntheses utilizing the cyclodehydration method to prepare novel tetrahydronaphthalenes substituted with functional groups at each position of the aromatic ring and various alkyl groups at the 1-position of the non-aromatic ring are described.

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

arene C-H bonds. Mechanistic experiments support the proposal of intramolecular elimination of methane followed by a concerted addition of the hydrocarbonC-Hbond. Products formed by activation of sp2 C-H bonds are generally more thermodynamically stable than those formed by activation of sp3 C-H bonds, and those resulting from reaction at primary C-H bonds are preferred over secondary sp3 C-H activation
