Check Digit Verification of cas no

The CAS Registry Mumber 67472-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,7 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67472-22:
(7*6)+(6*7)+(5*4)+(4*7)+(3*2)+(2*2)+(1*2)=144
144 % 10 = 4
So 67472-22-4 is a valid CAS Registry Number.

Photoredox Allylation Reactions Mediated by Bismuth in Aqueous Conditions

Potenti, Simone,Gualandi, Andrea,Puggioli, Alessio,Fermi, Andrea,Bergamini, Giacomo,Cozzi, Pier Giorgio

supporting information, p. 1624 - 1627 (2021/02/05)

Organometallic allylic reagents are widely used in the construction of C?C bonds by Barbier-type reactions. In this communication, we have described a photoredox Barbier allylation of aldehydes mediated by bismuth, in absence of other metals as co-reductants. Mild reaction conditions, tolerance of oxygen, and use of aqueous solvent make this photoredox methodology attractive for green and sustainable synthesis of homoallylic alcohols.

Copper-catalyzed radical oxyallylation of olefins for the construction of alkene-containing isoxazolines

He, Xiaoxue,Qian, Lijie,Dai, Yuyu,Yan, Xinhuan,Li, Xiaoqing,Xu, Xiangsheng

supporting information, (2021/05/31)

A radical-mediated approach to alkene oxyallylation using allylic oximes is described. The reaction proceeds under copper-catalytic redox-neutral conditions and tolerates various functional groups. This protocol thus enables the synthesis of structurally valuable isoxazolines and the introduction of a versatile olefin motif in a single step.

Nickel-Catalyzed Homo- And Cross-Coupling of Allyl Alcohols via Allyl Boronates

Gan, Yi,Hu, Hui,Liu, Yuanhong

supporting information, p. 4418 - 4423 (2020/06/27)

A nickel-catalyzed homo- and cross-coupling of allylic alcohols to 1,5-dienes in the presence of B2pin2 with excellent regioselectivity has been developed. Mechanistic studies indicate that the reaction proceeds via sequential nickel-catalyzed borylation of allyl alcohols followed by cross-coupling of the resulting allyl boronates with allyl alcohols. The method was effectively applied to nickel-catalyzed allylation of aldehydes using allylic alcohols directly.

Cp2TiCl2-Catalyzed Photoredox Allylation of Aldehydes with Visible Light

Bergamini, Giacomo,Calogero, Francesco,Cozzi, Pier Giorgio,Fermi, Andrea,Gualandi, Andrea,Guazzi, Simone,Mazzarini, Martino

, p. 3857 - 3863 (2020/03/26)

A Barbier-type Cp2TiCl2-mediated (10 mol %) photoredox allylation of aldehydes under irradiation with visible light (blue light-emitting diodes (LEDs), 450 nm) and in the presence of an organic dye (3DPAFIPN, 5 mol %) with allylbromides is described.

Nickel-Catalyzed Hydroarylation of in Situ Generated 1,3-Dienes with Arylboronic Acids Using a Secondary Homoallyl Carbonate as a Surrogate for the 1,3-Diene and Hydride Source

Hamaguchi, Takashi,Kawatsura, Motoi,Takahashi, Yoshiyuki,Tsuji, Hiroaki

supporting information, (2020/02/15)

The nickel-catalyzed hydroarylation of 1,3-dienes with arylboronic acids using a secondary homoallyl carbonate as a surrogate for the 1,3-diene and hydride source has been developed. The synthetic strategy allowed an efficient access to a wide array of hydroarylation products in high yields with high functional group compatibility without the use of an external hydride source. Mechanistic experiments indicated that the alkene-directed oxidative addition and subsequent β-hydride elimination would be a critical process in this transformation.

Copper-catalyzed asymmetric cyanation of alkenes via carbonyl-assisted coupling of alkyl-substituted carbon-centered radicals

Zhou, Song,Zhang, Guoyu,Fu, Liang,Chen, Pinhong,Li, Yibiao,Liu, Guosheng

supporting information, p. 6299 - 6303 (2020/10/02)

Based on a copper-catalyzed radical relay strategy, the first copper-catalyzed asymmetric cyanation of alkyl-substituted alkenes has been developed. The reaction, featuring mild reaction conditions and excellent functional group compatibilities, provides

Copper-Catalyzed Aerobic Cyclization of β,γ-Unsaturated Hydrazones with Concomitant CC Bond Cleavage

Fan, Zhenwei,Feng, Jiahao,Hou, Yuchen,Rao, Min,Cheng, Jiajia

supporting information, p. 7981 - 7985 (2020/11/02)

A Cu-catalyzed aerobic oxidative cyclization of β,γ-unsaturated hydrazones for the preparation of pyrazole derivatives has been developed. The hydrazonyl radical promoted the cyclization, along with a concomitant CC bond cleavage of β,γ-unsaturated hydrazones. This process has been verified via several control experiments, including a radical-trapping study, an 18O-labeling method, and the identification of the possible byproducts. The advantages of this reaction include operational simplicity, a broad reaction scope, and a mild selective reaction process.

Cationic Cobalt Porphyrin-Catalyzed Allylation of Aldehydes with Allyltrimethylsilanes

Tomifuji, Rei,Masuda, Shota,Kurahashi, Takuya,Matsubara, Seijiro

supporting information, p. 3834 - 3837 (2019/05/24)

Cationic cobalt porphyrin-catalyzed allylation of aldehydes with allyltrimethylsilanes is developed. The formation of the aldehyde-cobalt porphyrin complex, the key intermediate for the addition of allylsilanes, is confirmed by theoretical studies and syn

Allylation of aldehydes by dual photoredox and nickel catalysis

Gualandi, Andrea,Rodeghiero, Giacomo,Faraone, Adriana,Patuzzo, Filippo,Marchini, Marianna,Calogero, Francesco,Perciaccante, Rossana,Jansen, Thomas Paul,Ceroni, Paola,Cozzi, Pier Giorgio

supporting information, p. 6838 - 6841 (2019/06/18)

Here we report the application of dual nickel/photoredox catalysis to the allylation of aliphatic, aromatic and heteroaromatic aldehydes by using commercially available reagents. The process utilizes the combination of a Ni(ii) complex, [Ru(bpy)3]2+ as a photoredox catalyst, and allylacetate under blue LED irradiation, and allows the synthesis of a large variety of homoallylic alcohols.

Photocatalytic Barbier reaction-visible-light induced allylation and benzylation of aldehydes and ketones

Berger, Anna Lucia,Donabauer, Karsten,K?nig, Burkhard

, p. 7230 - 7235 (2018/10/02)

We report a photocatalytic version of the Barbier type reaction using readily available allyl or benzyl bromides and aromatic aldehydes or ketones as starting materials to generate allylic or benzylic alcohols. The reaction proceeds at room temperature under visible light irradiation with the organic dye 3,7-di(4-biphenyl)1-naphthalene-10-phenoxazine as a photocatalyst and DIPEA as sacrificial electron donor. The proposed cross-coupling mechanism of a ketyl- and an allyl or benzyl radical is supported by spectroscopic investigations and cyclic voltammetry measurements.
