2642-81-1 Usage

General Description

4,4'-DDNU, or 4,4'-Dinitrodiphenylurea, is a chemical compound with a high melting point that is soluble in hot ethanol and other organic solvents. It is usually found as a pale-yellow crystalline solid and can be synthesized easily. This organic compound is an aromatic chemical and falls under the classification of "urea derivatives". Its chemical structure sees two nitrophenyl groups bonded together by a urea group at opposing ends of the molecule and its chemical properties, such as reactivity and stability, are heavily influenced by the nitrophenyl and the urea moieties. It lacks study in its effects on the environment and human health.

Check Digit Verification of cas no

The CAS Registry Mumber 2642-81-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2642-81:
(6*2)+(5*6)+(4*4)+(3*2)+(2*8)+(1*1)=81
81 % 10 = 1
So 2642-81-1 is a valid CAS Registry Number.

Selective synthesis of iminodioxaspirononanes and diazaspirononanes using formic acid-activated Mn(III) oxidation of N1,N3-disubstitued malonamides with 1,1-diarylethenes

El-Deeb, Ibrahim Yussif,Nakano, Y?ki,Nishino, Hiroshi,Shimoishi, Ryutaro,Wada, Ryosei

, (2021/12/30)

The Mn(III)-based oxidation of N1,N3-disubstituted malonamides with alkenes by Kurosawa spirolactonization using malonic acid afforded iminodihydrofurans. A similar reaction with Mn(OAc)3, which was activated by HCO2

Intermolecular [4 + 2] process of N-acyliminium ions with simple olefins for construction of functional substituted-1,3-oxazinan-2-ones

An efficient approach to functionalized 4,6-disubstituted-and 4,6,6-trisubstituted-1,3-oxazinan-2-ones skeleton has been developed through the reaction of semicyclic N,O-acetals 4a and 4b with 1,1-disubstituted ethylenes 5 or 8. As a result of such a [4 +

Visible-Light-Induced Meerwein Fluoroarylation of Styrenes

Tang, Hai-Jun,Zhang, Bin,Xue, Fei,Feng, Chao

supporting information, p. 4040 - 4044 (2021/05/26)

An unprecedented approach for assembling a broad range of 1,2-diarylethane derivatives with fluorine-containing fully substituted carbon centers was developed. The protocol features straightforward operation, proceeds under metal-free condition, and accommodates a large variety of synthetically useful functionalities. The critical aspect to the success of this novel transformation lies in using aryldiazonium salts as both aryl radical progenitor and also as single electron acceptor which elegantly enables a radical-polar crossover manifold.
