42839-04-3 Usage

General Description

4-Pyrimidinecarbonitrile (7CI,9CI) is a chemical compound characterized as a derivative of pyrimidine. Pyrimidine is an aromatic heterocyclic compound very similar to pyridine, one of the most basic aromatic systems. However, specific information about 4-Pyrimidinecarbonitrile (7CI,9CI) such as its physical properties, uses, and health effects are not prominently available in public chemical databases. This implies that this compound may not be widely used in industrial or research applications, or it could still be under study. Pyrimidine derivatives, in general, are recognized for their various biological activities and are used in the field of medicinal chemistry to develop pharmaceutical drugs.

Check Digit Verification of cas no

The CAS Registry Mumber 42839-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,3 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42839-04:
(7*4)+(6*2)+(5*8)+(4*3)+(3*9)+(2*0)+(1*4)=123
123 % 10 = 3
So 42839-04-3 is a valid CAS Registry Number.

Electron-deficient heteroarenium salts: An organocatalytic tool for activation of hydrogen peroxide in oxidations

?turala, Ji?í,Bohá?ová, Soňa,Chudoba, Josef,Metelková, Radka,Cibulka, Radek

, p. 2676 - 2699 (2015/03/18)

A series of monosubstituted pyrimidinium and pyrazinium triflates and 3,5-disubstituted pyridinium triflates were prepared and tested as simple catalysts of oxidations with hydrogen peroxide, using sulfoxidation as a model reaction. Their catalytic efficiency strongly depends on the type of substituent and is remarkable for derivatives with an electron-withdrawing group, showing reactivity comparable to that of flavinium salts which are the prominent organocatalysts for oxygenations. Because of their high stability and good accessibility, 4-(trifluoromethyl)pyrimidinium and 3,5-dinitropyridinium triflates are the catalysts of choice and were shown to catalyze oxidation of aliphatic and aromatic sulfides to sulfoxides, giving quantitative conversions, high preparative yields and excellent chemoselectivity. The high efficiency of electron-poor heteroarenium salts is rationalized by their ability to readily form adducts with nucleophiles, as documented by low pKR+ values (pKR+ red > -0.5 V). Hydrogen peroxide adducts formed in situ during catalytic oxidation act as substrate oxidizing agents. The Gibbs free energies of oxygen transfer from these heterocyclic hydroperoxides to thioanisole, obtained by calculations at the B3LYP/6-311++g(d,p) level, showed that they are much stronger oxidizing agents than alkyl hydroperoxides and in some cases are almost comparable to derivatives of flavin hydroperoxide acting as oxidizing agents in monooxygenases.
