180780-15-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180780-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,8 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180780-15:
(8*1)+(7*8)+(6*0)+(5*7)+(4*8)+(3*0)+(2*1)+(1*5)=138
138 % 10 = 8
So 180780-15-8 is a valid CAS Registry Number.

Photo-induced oxidative cleavage of C-C double bonds for the synthesis of biaryl methanoneviaCeCl3catalysis

Xie, Pan,Xue, Cheng,Du, Dongdong,Shi, SanShan

, p. 6781 - 6785 (2021)

A Ce-catalyzed strategy is developed to produce biaryl methanonesviaphotooxidative cleavage of C-C double bonds at room temperature. This reaction is performed under air and demonstrates high activity as well as functional group tolerance. A synergistic Ce/ROH catalytic mechanism is also proposed based on the experimental observations. This protocol should be the first successful Ce-catalyzed photooxidation reaction of olefins with air as the oxidant, which would provide inspiration for the development of novel Ce-catalyzed photochemical synthesis processes.

Ni and Cu-catalyzed one pot synthesis of unsymmetrical 1,3-di(hetero)aryl-1: H -indazoles from hydrazine, o -chloro (hetero)benzophenones, and (hetero)aryl bromides

Wiethan, Carson,Lavoie, Christopher M.,Borzenko, Andrey,Clark, Jillian S. K.,Bonacorso, Helio G.,Stradiotto, Mark

supporting information, p. 5062 - 5069 (2017/07/11)

The nickel-catalyzed cyclization of in situ generated ortho-chlorobenzophenone hydrazone derivatives, to afford 3-(hetero)aryl-1H-indazoles, is documented for the first time. The product 1H-indazoles can be transformed subsequently in a one-pot procedure into 1,3-di(hetero)aryl-1H-indazoles via copper-catalyzed N-arylation with (hetero)aryl bromides.
