41103-85-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41103-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,0 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41103-85:
(7*4)+(6*1)+(5*1)+(4*0)+(3*3)+(2*8)+(1*5)=69
69 % 10 = 9
So 41103-85-9 is a valid CAS Registry Number.

Asymmetric Induction in the Reaction of a Chiral Lithiated Sulphoxide and Aldehydes

House, Stewart,Jenkins, Paul R.,Fawcett, John,Russell, David R.

, p. 1844 - 1845 (1987)

Significant asymmetric induction has been observed in the reaction of 1-lithio-2-phenyl-1-(R)-p-tolylsulphinylethylene; the sense of this induction has been established by an X-ray structure on one of the products.

Visible-light-induced selective synthesis of sulfoxides from alkenes and thiols using air as the oxidant

Cui, Huanhuan,Wei, Wei,Yang, Daoshan,Zhang, Yulong,Zhao, Huijuan,Wang, Leilei,Wang, Hua

supporting information, p. 3520 - 3524 (2017/08/15)

A highly selective synthesis of sulfoxides from alkenes and thiols was established by visible-light photoredox catalysis at room temperature. This metal-free transformation protocol, which uses inexpensive Rose Bengal as the photocatalyst and air as the green oxidant, opens a new door toward the facile and practical construction of sulfoxides.

Stereoselective heck reactions with vinyl sulfoxides, sulfides and sulfones

Bachmann, Daniel G.,Wittwer, Christopher C.,Gillingham, Dennis G.

supporting information, p. 3703 - 3707 (2014/01/06)

We report the Heck cross-coupling of notoriously unreactive, but synthetically valuable olefins: vinyl sulfoxides, vinyl sulfones, and vinyl sulfides. Key findings include the importance of the sterically hindered (tri-tert-butyl)phosphine ligand and the unique effectiveness of triethylamine as the base. The method is general, E-selective, and can be used to synthesize disubstituted or trisubstituted olefins through simple adjustments of stoichiometry. Copyright
