50415-59-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50415-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,4,1 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50415-59:
(7*5)+(6*0)+(5*4)+(4*1)+(3*5)+(2*5)+(1*9)=93
93 % 10 = 3
So 50415-59-3 is a valid CAS Registry Number.

Electrochemical oxidative: Z -selective C(sp2)-H chlorination of acrylamides

Coles, Simon J.,Hareram, Mishra Deepak,Harnedy, James,Morrill, Louis C.,Tizzard, Graham J.

, p. 12643 - 12646 (2021/12/07)

An electrochemical method for the oxidative Z-selective C(sp2)-H chlorination of acrylamides has been developed. This catalyst and organic oxidant free method is applicable across various substituted tertiary acrylamides, and provides access to a broad range of synthetically useful Z-β-chloroacrylamides in good yields (22 examples, 73% average yield). The orthogonal derivatization of the products was demonstrated through chemoselective transformations and the electrochemical process was performed on gram scale in flow.

Cobalt-Catalyzed Vinylic C-H Addition to Formaldehyde: Synthesis of Butenolides from Acrylic Acids and HCHO

Yu, Shuling,Hong, Chao,Liu, Zhanxiang,Zhang, Yuhong

supporting information, p. 8359 - 8364 (2021/11/01)

A carboxyl-assisted C-H functionalization of acrylic acids with formaldehyde to give butenolides is described. It is the first time that the addition of an inert vinylic C-H bond to formaldehyde has been achieved via cobalt-catalyzed C-H activation. The unique reactivity of the cobalt species was observed when compared with related Rh or Ir catalysts. γ-Hydroxymethylated butenolides were produced by the treatment of Na2CO3 after the catalytic reaction in one pot.

Palladium-catalyzed intermolecular C-H silylation initiated by aminopalladation

Ji, Xiaoming,Wei, Feng,Wan, Bin,Cheng, Cang,Zhang, Yanghui

, p. 7801 - 7804 (2020/07/27)

A Pd(ii)-catalyzed intermolecular C-H silylation reaction initiated by aminopalladation has been developed. The C-H bonds were activated by an alkyl Pd(ii) species generated through aminopalladation and then disilylated with hexamethyldisilane to form disilylated indolines as the final products. The reaction provides a new method for the introduction of silyl groups into complex organic molecules.
