873-49-4 Usage

General Description

Cyclopropylbenzene is a cyclopropylarene and its oxidation by rabbit liver microsomal cytochrome P-450 has been studied. Gas-phase structure of cyclopropylbenzene has been studied by ab initio computational, microwave spectroscopic and electron diffraction techniques.

Check Digit Verification of cas no

The CAS Registry Mumber 873-49-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 873-49:
(5*8)+(4*7)+(3*3)+(2*4)+(1*9)=94
94 % 10 = 4
So 873-49-4 is a valid CAS Registry Number.

Scalable On-Demand Production of Purified Diazomethane Suitable for Sensitive Catalytic Reactions

Sheeran, Jillian W.,Campbell, Kiersten,Breen, Christopher P.,Hummel, Gerald,Huang, Changfeng,Datta, Anamika,Boyer, Serge H.,Hecker, Scott J.,Bio, Matthew M.,Fang, Yuan-Qing,Ford, David D.,Russell, M. Grace

, p. 522 - 528 (2021/02/03)

We have developed a convenient development-scale reactor (0.44 mol/h) to prepare diazomethane from N-methyl-N-nitroso-p-toluenesulfonamide (MNTS) in ~80% yield. Diazomethane (CH2N2) made with this reactor is extracted into nitrogen gas from the liquid reaction mixture, effectively removing it from reagents and byproducts that may interfere in subsequent reactions. Vertically oriented tubular reactors were used to produce and consume diazomethane in situ. Key features of this reactor include high productivity and correspondingly low reactor volume (reactor volume/liquid flow rate = 6.5 min) and a commercially available gas/liquid separator equipped with a selectively permeating hydrophilic membrane. The design of the reactor keeps the inventory below 53 mg of CH2N2 during normal operation. The reactor was demonstrated by generating CH2N2 that was used in a connected continuous reactor. We evaluated esterification reactions and a continuous Pd-catalyzed cyclopropanation reaction with the reactor and achieved high conversion with 1.5 and 4.1 equiv of MNTS precursor, respectively.

Zn-Mediated Hydrodeoxygenation of Tertiary Alkyl Oxalates

Ye, Yang,Ma, Guobin,Yao, Ken,Gong, Hegui

supporting information, p. 1625 - 1628 (2021/01/18)

Herein we describe a general, mild, and scalable method for hydrodeoxygenation of readily accessible tertiary alkyl oxalates by Zn/silane under Ni-catalyzed conditions. The reduction method is suitable for an array of structural motifs derived from tertiary alcohols that bear diverse functional groups, including the synthesis of a key intermediate en route to estrone.
