Check Digit Verification of cas no

The CAS Registry Mumber 141377-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,3,7 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141377-54:
(8*1)+(7*4)+(6*1)+(5*3)+(4*7)+(3*7)+(2*5)+(1*4)=120
120 % 10 = 0
So 141377-54-0 is a valid CAS Registry Number.

Rapid microwave-assisted Henry reaction in solvent-free processes

Gan, Changsheng,Chen, Xing,Lai, Guoyin,Wang, Zhiyong

, p. 387 - 390 (2006)

The solvent-free Henry reactions of nitromethane with a series of carbonyl compounds were studied under microwave irradiation. By using different bases and Lewis acids, the solvent-free nitroaldol reaction of aldehydes were realized under microwave condition, affording the corresponding adducts with high yields. Particularly, aliphatic ketones, which were hardly carried out this reaction, could be the reaction substrates in the nitroaldol reactions by employment of 1,4-diazabicyclo[2.2.2]octane (DABCO) under a similar conditions, giving the corresponding adducts with moderate to good yields.

Henry reactions of nitroalkanes can be initiated with diethylzinc in the presence of catalytic amounts of 1,2-aminoethanol or 1,2-diaminoethane.

Indium-catalyzed henry-type reaction of aldehydes with bromonitro-alkanes

Soengas, Raquel G.,Silva, Artur M. S.

, p. 873 - 876 (2012)

An economical method to perform the addition of bromonitroalkanes to aldehydes using zinc in the presence of a catalytic amount of indium is established. This procedure affords the corresponding nitroalkanols in good yields and can be easily scaled up to

Urea-pyridine bridged periodic mesoporous organosilica: An efficient hydrogen-bond donating heterogeneous organocatalyst for Henry reaction

Borah, Parijat,Mondal, John,Zhao, Yanli

, p. 129 - 134 (2015)

Hydrogen-bond donating (HBD) organocatalysts have been employed as an important class of catalysts for the activation of small molecules. However, the use of these catalysts was restricted on account of the self-aggregation of HBD-active species. In this work, a successful approach was developed to construct novel urea-pyridine bridged periodic mesoporous organosilica (PMO) to prevent the unwanted self-recognition and aggregation of urea-based catalytic center by spatial isolation, unleashing its HBD organocatalytic activity along with cooperative effect from the pyridine unit for efficient Henry reaction. The urea-pyridine bridged PMO catalyst presents high structural stability and high catalytic recyclability.

Mg-NHC complex on the surface of nanomagnesium oxide for catalytic application

Shaikh, Melad,Sahu, Mahendra,Gavel, Pramod Kumar,Turpu, Goverdhan Reddy,Khilari, Santimoy,Pradhan, Debabrata,Ranganath, Kalluri V.S.

, p. 89 - 92 (2016)

We have developed a simple and eco-friendly protocol for the synthesis of Mg-NHC complexes. The Mg-NHC complex is prepared by reacting nano-MgO with imidazolium salts. Thus prepared Mg-NHC complex has been realized in two divergent reactions one in C-C bond formation and other in dehydration reaction. Further, the Mg-NHC catalyst has been characterized by SEM, TEM, XPS, Raman Spectroscopy and XRD analysis.

Dendronized piperidine: Highly effective and recyclable catalysts for Henry reaction

Yi, Bing,Yin, Yanyan,Yi, Ziqi,Zhou, Wei,Liu, Haitao,Tan, Nianyuan,Yang, Hai

, p. 2320 - 2323 (2016)

Two types of dendronized tertiary amines were synthesized by attaching piperidine to the core of a Fréchet-type dendrimer or to the end of an alkyl chain that is linked to the dendritic core. The relationship between structure and property of the catalysts in the Henry reaction of 2-nitrobenzaldehyde and nitromethane was established. It was observed that the attachment of piperidine to the dendritic sector by using a hexamethylene chain effectively avoids the scenario of dendritic shell encapsulation. And the 4-G3′ catalyst of third-generation with dendritic link exhibits excellent catalytic performance, and can be recycled ten times without a significant loss of activity.

Electrochemically induced Henry reaction of nitromethane and carbonyl compounds

Chemoselective Henry reaction catalyzed by electro-generated base

Saraswat,Sharma,Singh,Siddiqui,Singh

, p. 1393 - 1399 (2013)

Chemoselective synthesis of 2-nitroalkanols catalyzed by electro-generated base (EGBs) in the presence of acetonitrile and lithium perchlorate has been studied by cyclic voltammetry and controlled potential electrolysis techniques. Cathodic reduction of nitromethane at platinum cathode produces organic anion which acts as EGBs and undergoes condensation with carbonyl group of substituted aldehydic substrate to produce 2-nitroalkanols in 75-85 % yields. The controlled nucleophilicity of EGBs in organic solvent during electrochemical reaction makes it chemoselective which is a unique feature of this work.

Revisit to Henry reaction by non conventional heterogeneous and efficient catalyst for nitroalcohol synthesis

Jadhav, Swati D.,Patil, Rupesh C.,Jagdale, Ashutosh A.,Patil, Suresh S.

, p. 593 - 606 (2021/11/03)

A sustainable, green and efficient process for the synthesis of 2-nitro alcohol derivatives from different substituted aromatic aldehydes with nitroalkane by stirring at ambient temperature with high product yield is reported. Adoption of very mild reaction conditions, use of Calcined Eggshell (CES) as natural catalyst and simple workup are expected to contribute to the development of environmentally benign synthetic method for Henry (nitroaldol) reaction. CES is ecologically safe, inexpensive, and attractive heterogeneous base catalyst obtained from renewable resources, thus opening a new perspective for this process.
