Check Digit Verification of cas no

The CAS Registry Mumber 25855-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25855-20:
(7*2)+(6*5)+(5*8)+(4*5)+(3*5)+(2*2)+(1*0)=123
123 % 10 = 3
So 25855-20-3 is a valid CAS Registry Number.

2-Chloroquinazoline. Synthesis and reactivity of a versatile heterocyclic building block

Henriksen, Signe Teuber,S?rensen, Ulrik Svane

, p. 8251 - 8254 (2006)

Starting from 2,4-dichloroquinazoline, various methods for the selective removal of the 4-chloro substituent were tested, including catalytic hydrogenation, metal-halogen exchange, metal hydride reduction and reduction with tributyltin hydride-the latter

BTP-Rh@g-C3N4 as an efficient recyclable catalyst for dehydrogenation and borrowing hydrogen reactions

Luo, Lan,Liu, Hongqiang,Zeng, Wei,Hu, Wenkang,Wang, Dawei

, (2021/11/16)

Highly active catalysts play an important role in modern catalysis. A novel and efficient ligand benzotriazole-pyrimidine (BTP) and the corresponding rhodium composite on C3N4 were successfully synthesized. The resulting rhodium composite was fully characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray diffraction (XRD), thermogravimetric analysis (TGA), and x-ray photoelectron spectroscopy (XPS). The obtained composite exhibited good catalytic activity and good recovery performance in the synthesis of quinoxaline from 2-aminobenzyl alcohol and benzonitrile, and more than 20 quinoxalines were obtained in good yields. Additionally, it also showed that rhodium composite could achieved good catalytic performance in the synthesis of functionalized ketone through borrowing hydrogen strategy.

Paragraph 0057-0060, (2022/01/24)

The invention discloses a method for catalyzing nitrogen heterocycle aerobic dehydrogenation based on an ionic liquid porous carbon material, and is suitable for the field of organic synthesis. A heterogeneous catalysis system takes nitrogen heterocycle and derivatives thereof as substrates, a carbon material as a catalyst, water or ethanol as a solvent and air or oxygen spheres as an oxygen source, and a reaction is carried out at 0-80 DEG C under normal pressure, oxidative dehydrogenation of nitrogen heterocyclic compounds can be realized, and target products such as indole, quinoline, isoquinoline, quinazoline, quinoxaline, benzothiazole, Hanus ester and derivatives thereof and other medical intermediates can be synthesized. The non-metal catalyst is prepared by using the ionic liquid as the precursor, no activating agent or other additives are used in the reaction process, and the method has industrial application prospects.

Treatment of N,N,O-tridentate pyrazolyl-pyridinyl-alcohol ligands, 2-(CR1R2OH)-6-[3,5-(R3)2C3HN2]C5H3N (R1 = R2 = Me, R3 = H (L1H); R1 = Me, R2 = Ph, R3 = H (L2H); R1 = R2 = Ph, R3 = H (L3H); R1 = R2 = R3 = Me (L4H)) with RuCl3?xH2O in refluxing EtOH afforded the corresponding Ru(III) complexes L2RuCl (1a-1d), which were well characterized by IR, HR-MS and X-ray single crystal structural determination. These Ru complexes showed similarly high catalytic performance for both dehydrogenative couplings of 2-aminoarylmethanols with ketones and nitriles, giving the quinolines and quinazolines in good to excellent yields. This protocol provides an atom-economical and sustainable route to access various structurally important quinoline and quinazoline derivatives by using phosphine-free ligand based Ru catalysts.

Benzothiazole-doped porous organic polymers (POP-MBTS) were synthesized from a copolymerization reaction of 2-(6-(4-vinylphenyl)pyridin-2-yl)benzo[d]thiazole with divinylbenzene. The corresponding POP-MBTS-Ir was obtained and fully characterized using SEM, TEM, EDS, TGA, XPS, and N2 sorption isotherms, which disclosed that this catalyst has a high surface area, hierarchical porosity, and thermodynamic stability. Importantly, this catalyst revealed a high catalytic activity for ten different kinds of borrowing hydrogen and dehydrogenation reactions in water with a good recovery performance. Furthermore, mechanistic investigations were conducted for the synthesis of triazine derivatives.

Mixed crystalline phases and catalytic performance of OMS-2 based nanocomposites for one-pot synthesis of quinazolines with O2 as an oxidant

Yao, Nan,Bi, Xiuru,Zhang, Liping,Tao, Luyao,Zhao, Peiqing,Meng, Xu,Liu, Xiang

, (2021/03/03)

In this work, a series of sodium phosphotungstate modified manganese oxide octahedral molecular sieve (OMS-2) catalysts ([PW]-OMS-2) were developed, and their catalytic activities were investigated by one-pot synthesis of quinazolines from benzyl alcohol and 2-aminobenzylamine with O2 as green oxidant in dimethyl carbonate (DMC). TEM, XRD and EDS confirmed that sodium phosphotungstate decomposed into phosphotungstic acid and sodium tungstate in the doping process. Meanwhile, phosphotungstic acid attached and located at the surface of OMS-2 and W ions were successfully doped into the OMS-2 framework. For comparison, phosphotungstic acid/OMS-2 was prepared by simple wet impregnation method. The [PW]-OMS-2 is the most highly selective and effective over than phosphotungstic acid/OMS-2 and OMS-2 itself in the one-pot synthesis of quinazolines. It may be due to the synergetic effect of phosphotungstic acid and OMS-2, and successfully doping W into OMS-2 frameworks. Hence, this work provides a new environmentally-friendly and heterogeneous OMS-2 based nanocomposites and it may be put into practice to synthesize heterocyclic compounds.
