139057-16-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139057-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139057-16:
(8*1)+(7*3)+(6*9)+(5*0)+(4*5)+(3*7)+(2*1)+(1*6)=132
132 % 10 = 2
So 139057-16-2 is a valid CAS Registry Number.

Bronsted acid catalyzed PhSe transfer versus radical aryl transfer: Linear codimerization of styrenes and internal olefins

Bronsted acid p-TsOH·H2O-catalyzed hydrovinylation of styrenes with internal olefins α-oxo ketene dithioacetals was efficiently achieved in the presence of N-phenylselenophthalimide (N-PSP), regioselectively affording Markovnikov phenylselenati

Copper-catalyzed trifluoromethylation of internal olefinic C-H bonds: Efficient routes to trifluoromethylated tetrasubstituted olefins and N-heterocycles

Mao, Zhifeng,Huang, Fei,Yu, Haifeng,Chen, Jiping,Yu, Zhengkun,Xu, Zhaoqing

supporting information, p. 3439 - 3445 (2014/04/03)

The functionalization of internal olefins has been a challenging task in organic synthesis. Efficient CuII-catalyzed trifluoromethylation of internal olefins, that is, α-oxoketene dithioacetals, has been achieved by using Cu(OH)2 as a catalyst and TMSCF3 as a trifluoromethylating reagent. The push-pull effect from the polarized olefin substrates facilitates the internal olefinic C-H trifluoromethylation. Cyclic and acyclic dithioalkyl α-oxoketene acetals were used as the substrates and various substituents were tolerated. The internal olefinic C-H bond cleavage was not involved in the rate-determining step, and a mechanism that involves radicals is proposed based on a TEMPO-quenching experiment of the trifluoromethylation reaction. Further derivatization of the resultant CF 3 olefins led to multifunctionalized tetrasubstituted CF3 olefins and trifluoromethylated N-heterocycles.
