Chemical Properties

white to light yellow crystal powder

Uses

3,4-Dimethoxybenzonitrile is used as an organic chemical synthesis intermediate.

Preparation

Veratraldoxime(88–89 g, 0.45 mol) was combined with acetic anhydride (100 g) in a 300-mL round-bottomed flask equipped with a ground-glass air condenser, and the mixture was cautiously heated. A vigorous reaction took place, at which point the flame (heating by oil bath; the author) was removed. After the reaction had subsided, the solution was gently refluxed for 2 h and then carefully poured, with stirring, into cold water (300 mL). Stirring was continued, and on cooling the nitrile separated as small, almost colorless crystals; these were collected by filtration and dried in air. The veratronitrile thus obtained was quite pure; yield 57–62 g (72–76%); mp 66–67 C°. 1-Cyanoacenaphthene 1403 can be synthesized from its carbaldoxime by dehydration with acetic anhydride in 87% yield. Whereas acetic anhydride usually serves as the solvent as well as the reactant, this procedure is performed in n-octane.

Check Digit Verification of cas no

The CAS Registry Mumber 2024-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,2 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2024-83:
(6*2)+(5*0)+(4*2)+(3*4)+(2*8)+(1*3)=51
51 % 10 = 1
So 2024-83-1 is a valid CAS Registry Number.

Effect of crown ether macrocycle on the methylation of the thioamide derivatives of benzo-15-crown-5 and veratrole

Sayfullina,Tashmukhamedova,Shakhidoyatov

, p. 998 - 1001 (2003)

It was shown that benzo-15-crown-5 ether has an effect on the methylation of the thioamide derivatives. leading to the formation of the nitriles of carboxylic acids.

Inductively heated oxides inside microreactors - Facile oxidations under flow conditions

Wegner, Jens,Ceylan, Sascha,Friese, Carsten,Kirschning, Andreas

Inductively heated iron oxides mixed with solid oxidants like CrO 2 and NiO2 efficiently oxidize organic substrates under flow conditions in fixed-bed reactors.

SO2F2-mediated oxidation of primary and tertiary amines with 30% aqueous H2O2 solution

Liao, Xudong,Zhou, Yi,Ai, Chengmei,Ye, Cuijiao,Chen, Guanghui,Yan, Zhaohua,Lin, Sen

supporting information, (2021/11/01)

A highly efficient and selective oxidation of primary and tertiary amines employing SO2F2/H2O2/base system was described. Anilines were converted to the corresponding azoxybenzenes, while primary benzylamines were transformed into nitriles and secondary benzylamines were rearranged to amides. For tertiary amine substrates quinolines, isoquinolines and pyridines, their oxidation products were the corresponding N-oxides. The reaction conditions are very mild and just involve SO2F2, amines, 30% aqueous H2O2 solution, and inorganic base at room temperature. One unique advantage is that this oxidation system is just composed of inexpensive inorganic compounds without the use of any metal and organic compounds.

Nickel-Catalyzed Cyanation of Aryl Thioethers

Delcaillau, Tristan,Woenckhaus-Alvarez, Adrian,Morandi, Bill

supporting information, p. 7018 - 7022 (2021/09/13)

A nickel-catalyzed cyanation of aryl thioethers using Zn(CN)2 as a cyanide source has been developed to access functionalized aryl nitriles. The ligand dcype (1,2-bis(dicyclohexylphosphino)ethane) in combination with the base KOAc (potassium acetate) is essential for achieving this transformation efficiently. This reaction involves both a C-S bond activation and a C-C bond formation. The scalability, low catalyst and reagents loadings, and high functional group tolerance have enabled both late-stage derivatization and polymer recycling, demonstrating the reaction's utility across organic chemistry.
