Check Digit Verification of cas no

The CAS Registry Mumber 114546-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,5,4 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 114546-62:
(8*1)+(7*1)+(6*4)+(5*5)+(4*4)+(3*6)+(2*6)+(1*2)=112
112 % 10 = 2

Paragraph 0112-0116, (2021/11/14)

The water-soluble vitamin E participates in the green preparation method of the conjugated diyne compound, the water serves as a reaction solvent, the use amount of the organic solvent is reduced, and zero emission of the solvent is realized. The excellent physicochemical properties of water are fully utilized, the reaction conditions are mild and efficient, the surfactant TPGS - 750 - M can be recycled through treatment, and the principle of environmental friendliness is completely met. The reaction substrate is wide in applicability, can catalyze the aryl alkyne, can catalyze the aliphatic hydrocarbon, and provides a simple and environment-friendly preparation method for the synthesis of the conjugated diyne. The copper catalyst which is more suitable for the reaction and reaction medium of the invention is screened out, and the yield is greatly improved.

Rh(III)-Catalyzed [3 + 2] Spirocyclization of 2 H-Imidazoles with 1,3-Diynes for the Synthesis of Spiro-[imidazole-indene] Derivatives

An effective strategy to synthesize spirocyclic compounds, [imidazole-4,1′-indene], has been efficaciously developed relied on Rh(III)-catalyzed [3 + 2] spirocyclization of 2H-imidazoles and 1,3-diynes with excellent chemselectivity and regioselectivity.

Phosphorus(III)-Mediated, Tandem Deoxygenative Geminal Chlorofluorination of 1,2-Diketones

Choi, Garam,Chung, Won-Jin,Hwang, Sunjoo,Jang, Hanna,Kim, Ha Eun

supporting information, p. 4190 - 4195 (2020/06/27)

Tetrasubstituted carbon containing two different halogen substituents was constructed in a single-step operation by utilizing the carbene-like reactivity of dioxaphospholene through the tandem reaction of electrophilic and nucleophilic halogenating reagents. It was crucial to devise non-dealkylatable phosphoramidite, which enabled the efficient formation of geminal chlorofluorides from various 1,2-diketones with (PhSO2)2NF and n-Bu4NCl. In addition, selective functionalization of the chlorine substituent was demonstrated, and the absence of halogen scrambling was confirmed.

Metallomicelle catalyzed aerobic tandem desilylation/Glaser reaction in water

PEG-grafted nitrogen ligands were synthesized. The corresponding copper complexes serve as metallomicellar nanoreactors for the aerobic tandem desilylation/Glaser coupling of TMS-protected alkynes in water. The protocol is also suitable for base-free homocoupling of terminal alkynes. The metallomicellar catalyst could be recycled 5 times with minor loss of reactivity.

Stereoselective Synthesis of Highly Substituted Conjugated Dienes via Pd-Catalyzed Carbonylation of 1,3-Diynes

Liu, Jiawang,Yang, Ji,Baumann, Wolfgang,Jackstell, Ralf,Beller, Matthias

supporting information, p. 10683 - 10687 (2019/07/04)

The stereoselective synthesis of conjugated dienes was realized for the first time via Pd-catalyzed alkoxycarbonylation of easily available 1,3-diynes. Key to success is the utilization of the specific ligand 1,1′-ferrocenediyl-bis(tert-butyl(pyridin-2-yl)phosphine) (L1), which allows this novel transformation to proceed at room temperature. A range of 1,2,3,4-tetrasubstituted conjugated dienes are obtained in this straightforward access in high yields and selectivities. The synthetic utility of the protocol is showcased in the concise synthesis of several important intermediates for construction of natural products rac-cagayanin, rac-galbulin, rac-agastinol, and cannabisin G.

Continuous-flow oxidative homocouplings without auxiliary substances: Exploiting a solid base catalyst

?tv?s, Sándor B.,Georgiádes, ádám,Mészáros, Rebeka,Kis, Koppány,Pálinkó, István,Fül?p, Ferenc

, p. 90 - 99 (2017/03/15)

The catalytic oxidative dimerization of aromatic amines and acetylenes is of outstanding synthetic importance among homocoupling reactions. Both transformations necessitate the use of extraneous bases and ligands, which contains significant disadvantages as concerns environmental impacts and process costs. We exploited the inherent basic character of a copper-containing layered double hydroxide to facilitate the catalytic homocouplings of alkynes and aniline derivatives without the need for any auxiliary substances. The reactions were studied in a continuous-flow system to achieve extended parameter spaces for chemical intensification, and also to avoid undesired reaction pathways by means of strategic control over the residence time. Valuable 1,4-disubstituted 1,3-diynes and diversely substituted aromatic azo compounds were achieved chemoselectively in excellent yields and in short process times even on preparative scales.
