Check Digit Verification of cas no

The CAS Registry Mumber 1692-39-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1692-39:
(6*1)+(5*6)+(4*9)+(3*2)+(2*3)+(1*9)=93
93 % 10 = 3
So 1692-39-3 is a valid CAS Registry Number.

1,3-Oxyalkynylation of Aryl Cyclopropanes with Ethylnylbenziodoxolones Using Photoredox Catalysis

Studer, Armido,Zuo, Zhijun

supporting information, p. 949 - 954 (2022/02/07)

Alkynes and cyclopropanes are vital motifs in chemistry. Herein, a photoredox catalyzed 1,3-oxyalkynylation of aryl cyclopropanes with ethylnylbenziodoxolones (EBXs) in an atom-economic fashion is described. This cascade comprises single-electron oxidatio

Rational design of a gold carbene precursor complex for a catalytic cyclopropanation reaction

Ringger, David H.,Chen, Peter

, p. 4686 - 4689 (2013/06/05)

Bridging gas- and solution-phase chemistry: A gold(I) carbene precursor complex has been developed and investigated for catalytic cyclopropanation. Formation of the carbene intermediate was first probed by mass spectrometry, followed by cyclopropanation of p-methoxystyrene in solution. The imidazolylidene leaving group serves as a base generated in situ that is necessary in the putative catalytic cycle. Copyright

Cyclopropanation with gold(I) carbenes by retro-Buchner reaction from cycloheptatrienes

Solorio-Alvarado, César R.,Wang, Yahui,Echavarren, Antonio M.

, p. 11952 - 11955 (2011/10/04)

Cationic gold(I) promotes the retro-Buchner reaction of 7-substituted 1,3,5-cycloheptatrienes, leading to gold(I) carbenes that cyclopropanate alkenes.

Redox-photosensitized aminations of 1,2-benzo-1,3-cycloalkadienes, arylcyclopropanes, and quadricyclane with ammonia

Yasuda, Masahide,Kojima, Ryuji,Tsutsui, Hiroshi,Utsunomiya, Daigo,Ishii, Kazuaki,Jinnouchi, Koutaro,Shiragami, Tsutomu

, p. 7618 - 7624 (2007/10/03)

1,2,4-Triphenylbenzene and 2,2′-methylenedioxy-1,1′ -binaphthalene successfully photosensitized the aminations of 1,2-benzo-1,3-cycloalkadienes, arylcyclopropanes, and quadricyclane with ammonia and primary amines in the presence of m- or p-dicyanobenzene, which gave the 4-amino-1,2-benzocycloalkenes, 3-amino-1-arylpropanes, and 7-amino-5-(p-cyanophenyl)bicyclo[2.2.1]hept-2-ene, respectively. A key pathway for the photosensitized amination is the hole transfer from the cation radicals of the sensitizers that were generated by photoinduced electron transfer to the electron acceptors to the substrates. Therefore, it was found that the relationships in oxidation potentials between the sensitizers and the substrates and the positive charge distribution of the cation radicals of the substrates were important factors for the efficient amination.

Kinetic Study of the Homolytic Brominolysis of 1,2-Diarylcyclopropanes

Applequist, Douglas E.,Gdanski, Rick D.

, p. 2502 - 2510 (2007/10/02)

The rate constants for the photolytic brominolysis of 22 trans-1,2-diarylcyclopropanes in carbon disulfide relative to an internal standard, p-chlorotoluene, have been determined.The products of the brominolysis are 1,3-dibromo-1,3-diarylpropanes.The rate constants range over 5 orders of magnitude, being enhanced by electrondonating substituents on one or both benzene rings.The quantitative size of the substituent effect (ρ) at either involved carbon center is a function of the substituent at the other center.This fact suggests a continuum of transition-state structures with varying degrees of bond breaking and charge separation.
