40491-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40491-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,9 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40491-23:
(7*4)+(6*0)+(5*4)+(4*9)+(3*1)+(2*2)+(1*3)=94
94 % 10 = 4
So 40491-23-4 is a valid CAS Registry Number.

Easy access to secondary and tertiary alcoholsviametal-free and light mediated radical carbonyl allylation

Das, Mrinmoy,Lee, Jiande,Lin, Junjie Desmond,Liu, Xue-Wei,Pal, Kumar Bhaskar,Xu, Yuan,Yip, Benjamin Rui Peng

supporting information, p. 10783 - 10786 (2021/10/20)

Here we report a strategy for carbonyl addition with unactivated alkenes using an organic photocatalyst on both aldehyde and ketone substrates. This protocol grants us a good alternative to the traditional Barbier-Grignard allylation that exhibits poor functional group tolerance. With this method the stoichiometric use of metals can be avoided, high atom economy can be achieved and fewer by-products are generated.

Iron-catalysed 1,2-aryl migration of tertiary azides

Wei, Kaijie,Yang, Tonghao,Chen, Qing,Liang, Siyu,Yu, Wei

, p. 11685 - 11688 (2020/10/19)

1,2-Aryl migration of α,α-diaryl tertiary azides was achieved by using the catalytic system of FeCl2/N-heterocyclic carbene (NHC) SIPr·HCl. The reaction generated aniline products in good yields after one-pot reduction of the migration-resultant imines.
