General Description

N,4'-Dimethylformanilide, also known as N,N-dimethyl-p-toluidide, is a chemical compound with the formula C10H13NO. It is a pale yellow to brown liquid that is commonly used as a reagent in organic synthesis. N,4'-Dimethylformanilide is often used as a solvent in chemical reactions due to its high boiling point and low reactivity. It is also used as a precursor for the synthesis of various pharmaceuticals and dyes. Additionally, it is a key intermediate in the production of certain agricultural chemicals. However, it should be handled with caution as it is toxic if inhaled, swallowed, or absorbed through the skin, and can cause skin and eye irritation.

Check Digit Verification of cas no

The CAS Registry Mumber 2739-04-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,3 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2739-04:
(6*2)+(5*7)+(4*3)+(3*9)+(2*0)+(1*4)=90
90 % 10 = 0
So 2739-04-0 is a valid CAS Registry Number.

Acid-catalyzed chemodivergent reactions of 2,2-dimethoxyacetaldehyde and anilines

Guo, Luxia,Chen, Zihao,Zhu, Hongmei,Li, Minghao,Gu, Yanlong

supporting information, p. 1419 - 1422 (2020/11/12)

Chemodivergent reactions of 2,2-dimethoxyacetaldehyde and anilines were described, which were established on the basis of either a C[sbnd]C bond cleavage or a rearrangement process of a reaction intermediate. These reactions proceeded in a condition-determined manner with good functional group tolerance. In the first model, 2,2-dimethoxyacetaldehyde reacted with aniline to form a new C[sbnd]N bond, in the presence of O2, via a C[sbnd]C bond cleavage reaction. However, in the second model, by performing the reaction in the absence of O2, Heyns rearrangement occurred and generated a new C[sbnd]O bond to form methyl phenylglycinate. Such condition-determined reactions not only offered the new way for value-added conversion of biomass-derived platform molecule, 2, 2-dimethoxyacetaldehyde, but also provided efficient methods for the synthesis of N-arylformamides and methyl phenylglycinates.

Recyclable Oxofluorovanadate-Catalyzed Formylation of Amines by Reductive Functionalization of CO2 with Hydrosilanes

Wu, Shanxuan,Huang, Zijun,Jiang, Xiaolin,Yan, Fachao,Li, Yuehui,Du, Chen-Xia

, p. 1763 - 1766 (2021/03/01)

An efficient method has been developed for the reductive amination of CO2 by using readily available and recyclable oxofluorovanadates as catalysts. Various amines are transformed into the desired N-formylated products in moderate to excellent yields at room temperature in the presence of phenylsilane. Mechanistic studies based on in situ infrared spectroscopy suggest a reaction pathway initiated through F?Si interactions. The activated phenylsilane allows for CO2 insertion to produce phenylsilyl formate, which undergoes attack by the amine to generate the target product.

Ionization of Porous Hypercrosslinked Polymers for Catalyzing Room-Temperature CO2 Reduction via Formamides Synthesis

Ren, Qinggang,Chen, Yaju,Qiu, Yongjian,Tao, Leiming,Ji, Hongbing

, p. 2919 - 2927 (2021/02/01)

Porous materials with heterogeneous nature occupy a pivotal position in the chemical industry. This work described a facile pre- and post-synthetic approach to modify porous hypercrosslinked polymer with quaternary ammonium bromide, rendering it as efficient catalyst for CO2 conversion. The as-prepared porous ionic polymer (PiP@QA) displayed an improved specific surface area of 301 m2·g?1 with hierarchically porous structure, good selective adsorption of CO2, as well as high ion density. Accordingly, PiP@QA catalyst exhibited excellent catalytic performances for the solvent-free synthesis of various formamides from CO2, amines and phenylsilane under 35?°C and 0.5?MPa. We speculated that the superior catalytic efficiency and broad substrate scope of this catalyst could be resulted from the synergistic effect of flexible ionic sites with unique nanoporous channel that might increase the collision probability of reactants and active sites as well as enhance the diffusion of reactants and products during the reaction process. With the good reusability, PiP@QA was also available for the efficient conversion of simulated flue gas (15% CO2 in N2, v/v) into target formamides with quantitative selectivity at room temperature, which further highlighted its industrial application potential in chemical recycling the real-word CO2 to valuable products.
