Check Digit Verification of cas no

The CAS Registry Mumber 7381-89-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,8 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7381-89:
(6*7)+(5*3)+(4*8)+(3*1)+(2*8)+(1*9)=117
117 % 10 = 7
So 7381-89-7 is a valid CAS Registry Number.

Synthesis Method of Cyclopropane or Cyclopentene Derivatives via Fe-catalyzed Cationic Radical Cycloaddition Reaction

-

Paragraph 0080-0081; 0101-0102, (2021/11/02)

In this disclosure Fe (III) complex is used as an electron oxidizing agent to oxidize an electron - rich alkene compound to form a radical cation intermediate, and then a cyclopropane compound or 3 5-membered ring compound is synthesized by inducing a cycloaddition reaction with the diazo compound.

Cycloaddition Reactions of Alkene Radical Cations using Iron(III)-Phenanthroline Complex

Cho, Yong Hyun,Kim, Jae Hyung,An, Hyeju,Ahn, Kwang-Hyun,Kang, Eun Joo

supporting information, p. 2183 - 2188 (2020/04/29)

Single electron oxidation of electron-rich alkenes using the iron(III)-phenanthroline complex produced electrophilic alkene radical cations, which promoted efficient radical cation [2+1] cycloaddition reactions with diazo compounds. Subsequent chain propagation afforded tri- and tetra-substituted cyclopropanes. This methodology was also expanded to [3+2] cycloaddition reactions with vinyl diazoesters, validating this sustainable, first-row transition metal iron system for the single electron redox reactions. (Figure presented.).

A transition-metal-free & diazo-free styrene cyclopropanation

Herraiz, Ana G.,Suero, Marcos G.

, p. 9374 - 9379 (2019/10/22)

An operationally simple and broadly applicable novel cyclopropanation of styrenes using gem-diiodomethyl carbonyl reagents has been developed. Visible-light triggered the photoinduced generation of iodomethyl carbonyl radicals, able to cyclopropanate a wide array of styrenes with excellent chemoselectivity and functional group tolerance. To highlight the utility of our photocyclopropanation, we demonstrated the late-stage functionalization of biomolecule derivatives.

Cyclopropane-alkene metathesis by gold(i)-catalyzed decarbenation of persistent cyclopropanes

Mato, Mauro,Martín-Torres, Inmaculada,Herlé, Bart,Echavarren, Antonio M.

supporting information, p. 4216 - 4219 (2019/05/06)

A gold(i)-catalyzed cyclopropane-alkene metathesis has been demonstrated with two new families of cyclopropane derivatives of naphthalene and phenanthrene (benzo-fused norcaradienes). In this process, metal carbene units are transferred from a persistent

Rhodium Porphyrin Catalyzed Regioselective Transfer Hydrogenolysis of C-C σ-Bonds in Cyclopropanes with iPrOH

Chen, Chen,Feng, Shiyu,Chan, Kin Shing

supporting information, p. 2582 - 2589 (2019/07/02)

A new rhodium porphyrin catalyzed regioselective transfer hydrogenolysis of both activated and unactivated cyclopropanes employing iPrOH as the hydrogen source was discovered. The reaction mechanism for the C-C σ-bond activation of cyclopropanes was identified through an initial radical substitution with rhodium(II) metalloporphyrin radical to give a rhodium porphyrin alkyl, followed by hydrogenolysis with iPrOH to give the corresponding acyclic alkanes and regenerate rhodium(II) metalloporphyrin radical.

Radical Cation Cyclopropanations via Chromium Photooxidative Catalysis

Sarabia, Francisco J.,Ferreira, Eric M.

supporting information, p. 2865 - 2868 (2017/06/07)

The chromium photocatalyzed cyclopropanation of diazo reagents with electron-rich alkenes is described. The transformation occurs under mild conditions and features specific distinctions from traditional diazo-based cyclopropanations (e.g., avoiding β-hydride elimination, chemoselectivity considerations, etc.). The reaction appears to work most effectively using chromium catalysis, and a number of decorated cyclopropanes can be accessed in generally good yields.

Spin-selective generation of triplet nitrenes: Olefin aziridination through visible-light photosensitization of azidoformates

Scholz, Spencer O.,Farney, Elliot P.,Kim, Sangyun,Bates, Desiree M.,Yoon, Tehshik P.

supporting information, p. 2239 - 2242 (2016/02/18)

Azidoformates are interesting potential nitrene precursors, but their direct photochemical activation can result in competitive formation of aziridination and allylic amination products. Herein, we show that visible-light-activated transition-metal comple

Elevated catalytic activity of ruthenium(II)-porphyrin-catalyzed carbene/nitrene transfer and insertion reactions with n-heterocyclic carbene ligands

Chan, Ka-Ho,Guan, Xiangguo,Lo, Vanessa Kar-Yan,Che, Chi-Ming

supporting information, p. 2982 - 2987 (2014/04/03)

Bis(NHC)ruthenium(II)-porphyrin complexes were designed, synthesized, and characterized. Owing to the strong donor strength of axial NHC ligands in stabilizing the trans Mi£CRR′/Mi£NR moiety, these complexes showed unprecedently high catalytic activity towards alkene cyclopropanation, carbene C-H, N-H, S-H, and O-H insertion, alkene aziridination, and nitrene C-H insertion with turnover frequencies up to 1950 min-1. The use of chiral [Ru(D4-Por)(BIMe)2] (1 g) as a catalyst led to highly enantioselective carbene/nitrene transfer and insertion reactions with up to 98 % ee. Carbene modification of the N terminus of peptides at 37 °C was possible. DFT calculations revealed that the trans axial NHC ligand facilitates the decomposition of diazo compounds by stabilizing the metal-carbene reaction intermediate.

Wittig reagents as metallocarbene precursors: In situ generated monocarbonyl iodonium ylides

Ho, Phyllis E.,Tao, Jason,Murphy, Graham K.

supporting information, p. 6540 - 6544 (2013/11/06)

A proof of concept study was undertaken to determine the suitability of monocarbonyl iodonium ylides (MCIYs) as metallocarbene precursors. Exposing Wittig reagents to iodosylbenzene results in a pseudo-Wittig reaction that generates MCIYs in situ. These ylides are intercepted by transition-metal catalysts to generate metallocarbenes, which then undergo either dimerization or cyclopropanation reactions with a variety of alkenes. Additionally, the reaction between diazoester-derived metallocarbenes and Wittig reagents afforded cross-coupling products, illustrating a new type of olefination reaction for phosphonium ylides. Monocarbonyl iodonium ylides (MCIYs) represent a possible alternative to the use diazoketones and -esters as metallocarbene precursors. Upon treatment with iodosylbenzene, a Wittig reagent will undergo ylide transfer to generate a MCIY in situ. In the presence of transition-metal catalysts, MCIYs serve as precursors to metallocarbenes, which undergo dimerization or cyclopropanation of alkenes. tfacac = trifluoroacetylacetonate. Copyright

1,3,5-Tris(thiocyanatomethyl)mesitylene as a Ligand. Pseudooctahedral molybdenum, manganese, and rhenium carbonyl complexes and copper and silver dimers. Copper-catalyzed carbene- and nitrene-transfer reactions

Martinez-Garcia, Hector,Morales, Dolores,Perez, Julio,Puerto, Marcos,Miguel, Daniel

experimental part, p. 6974 - 6985 (2010/09/06)

New molybdenum(0), molybdenum(II), manganese(I), rhenium(I), silver(I), and copper(I) complexes with the 1,3,5-tris(thiocyanatomethyl)mesitylene [Ms(CH2SCN)3] ligand have been synthesized and characterized by IR, NMR, and by X-ray diffraction (except for the rhenium complex). The Ms(CH2SCN)3 ligand coordinated with the molybdenum, manganese, and rhenium carbonyl fragments as a tripodal chelate. With copper and silver, dimeric dicationic species were obtained instead, with the Ms(CH2SCN)3 ligand acting simultaneously as a bidentate chelate and bridge. The [{Cu(Ms(CH2SCN)3)} 2][BAr′4]2 (BAr′4 = tetra(3,5-bis(trifluoromethyl)phenyl)borate) product is an excellent catalyst for cyclopropanation and aziridination of alkenes and cyclopropenation of alkynes by means of carbene- and nitrene-transfer reactions.
