67210-34-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67210-34-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,1 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67210-34:
(7*6)+(6*7)+(5*2)+(4*1)+(3*0)+(2*3)+(1*4)=108
108 % 10 = 8
So 67210-34-8 is a valid CAS Registry Number.

Solvent-mediated switching between oxidative addition and addition-oxidation: Access to β-hydroxysulfides and β-arylsulfones by the addition of thiols to olefins in the presence of Oxone

Moorthy, Jarugu Narasimha,Payra, Soumen,Yadav, Navin

, p. 582 - 591 (2022/01/22)

The reaction between aryl olefins and thiols in the presence of Oxone in toluene-water (9:1, v/v) affords β-hydroxy-2-arylethyl aryl sulfides smoothly by the interception of intermediary thiyl radicals with aryl olefins; the former are generated by the ox

Competition Between Cα-S and Cα-Cβ Bond Cleavage in β-Hydroxysulfoxides Cation Radicals Generated by Photoinduced Electron Transfer?

Lapi, Andrea,D'Alfonso, Claudio,Del Giacco, Tiziana,Lanzalunga, Osvaldo

, p. 1310 - 1321 (2021/06/07)

A kinetic and product study of the 3-cyano-N-methyl-quinolinium photoinduced monoelectronic oxidation of a series of β-hydroxysulfoxides has been carried out to investigate the competition between Cα-S and Cα-Cβ bond cleavage within the corresponding cation radicals. Laser flash photolysis experiments unequivocally established the formation of sulfoxide cation radicals showing their absorption band (λmax ≈ 520?nm) and that of 3-CN-NMQ? (λmax ≈ 390?nm). Steady-state photolysis experiments suggest that, in contrast to what previously observed for alkyl phenyl sulfoxide cation radicals that exclusively undergo Cα-S bond cleavage, the presence of a β-hydroxy group makes, in some cases, the Cα-Cβ scission competitive. The factors governing this competition seem to depend on the relative stability of the fragments formed from the two bond scissions. Substitution of the β-OH group with -OMe did not dramatically change the reactivity pattern of the cation radicals thus suggesting that the observed favorable effect of the hydroxy group on the Cα-Cβ bond cleavage mainly resides on its capability to stabilize the carbocation formed upon this scission.

Air-Induced Disulfenylation of Alkenes: Facile Synthesis of Vicinal Dithioethers

Chen, Danyao,Chen, Qian,Huang, Yuanting,Ou, Yingcong,Yan, Y.,Yu, Guodian

, p. 83 - 86 (2019/12/30)

A novel disulfenylation of alkenes with thiophenols and their corresponding disulfides by using air as the oxidant has been achieved. This transformation provides a facile and practical protocol for the synthesis of vicinal dithioethers under mild conditions.
