5658-46-8 Usage

General Description

The chemical "{[(2-methylprop-2-en-1-yl)oxy]methyl}benzene" is a compound with a molecular formula C11H16O. It is also known as isobutylbenzene and is a colorless liquid with a strong odor. This chemical is commonly used as a solvent in various industries, including the manufacture of paints, coatings, and adhesives. It is also used in the production of other chemicals and as a fragrance ingredient in perfumes and personal care products. Additionally, isobutylbenzene is used as a precursor in the synthesis of pharmaceuticals and agrochemicals. However, it is important to handle this chemical with care, as it is flammable and may cause irritation to the skin, eyes, and respiratory system upon exposure.

Check Digit Verification of cas no

The CAS Registry Mumber 5658-46-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5658-46:
(6*5)+(5*6)+(4*5)+(3*8)+(2*4)+(1*6)=118
118 % 10 = 8
So 5658-46-8 is a valid CAS Registry Number.

Contra-Thermodynamic Positional Isomerization of Olefins

Zhao, Kuo,Knowles, Robert R.

supporting information, p. 137 - 144 (2022/01/19)

A light-driven method for the contra-thermodynamic positional isomerization of olefins is described. In this work, stepwise PCET activation of a more substituted and more thermodynamically stable olefin substrate is mediated by an excited-state oxidant an

Synthesis of Piperidine Derivatives by Rhodium- Catalyzed Tandem Reaction of N-Sulfonyl-1,2,3-Triazole and Vinyl Ether

Yu, Sisi,An, Yuehui,Wang, Wenlin,Xu, Ze-Feng,Li, Chuan-Ying

supporting information, p. 2125 - 2130 (2018/04/17)

A chemoselective tandem reaction of 4-acyloxymethylene-1-sulfonyl-1,2,3-triazole and vinyl ether was reported, producing polysubstituted piperidine derivatives in up to 96% yield. The key intermediate N-sulfonyl 1-azadiene generated by migration of the OAc group to the α-imino rhodium carbene was isolated and a plausible mechanism was proposed. Several related ring systems were constructed from the highly functionalized products. (Figure presented.).

Olefin chemistry, through pericyclic reactions, polymerizations, oxidations, or reductions, has an essential role in the manipulation of organic matter. Despite its importance, olefin synthesis still relies largely on chemistry introduced more than three decades ago, with metathesis being the most recent addition. Here we describe a simple method of accessing olefins with any substitution pattern or geometry from one of the most ubiquitous and variegated building blocks of chemistry: alkyl carboxylic acids. The activating principles used in amide-bond synthesis can therefore be used, with nickel- or iron-based catalysis, to extract carbon dioxide from a carboxylic acid and economically replace it with an organozinc-derived olefin on a molar scale. We prepare more than 60 olefins across a range of substrate classes, and the ability to simplify retrosynthetic analysis is exemplified with the preparation of 16 different natural products across 10 different families.
