52287-58-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52287-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,8 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52287-58:
(7*5)+(6*2)+(5*2)+(4*8)+(3*7)+(2*5)+(1*8)=128
128 % 10 = 8
So 52287-58-8 is a valid CAS Registry Number.

Iron-catalyzed tandem one-pot addition and cyclization of the blaise reaction intermediate and nitroolefins: Synthesis of substituted NH-pyrroles from nitriles

Zhao, Mi-Na,Liang, Hao,Ren, Zhi-Hui,Guan, Zheng-Hui

supporting information, p. 221 - 226 (2013/03/13)

The iron-catalyzed addition and cyclization of the Blaise reaction intermediate and nitroolefins to synthesize highly functionalized NH-pyrroles in a tandem one-pot manner from nitriles has been developed. This reaction shows good functional group tolerance and affords a broad spectrum of substituted NH-pyrroles in good yields. Copyright

Ethylenediamine: A highly effective catalyst for one-pot synthesis of aryl nitroalkenes via henry reaction and dehydration

Yang, Jianxin,Dong, Jing,Lue, Xia,Zhang, Qiang,Ding, Wei,Shi, Xiaoxin

, p. 2827 - 2833 (2013/08/23)

Ethylenediamine (H2NCH2CH2NH2) was found to be a highly effective catalyst for the condensation of aryl aldehydes with nitromethane (or nitroethane). When 1%-2% (mol%) of ethylenediamine was used as the catalyst, the one-pot reaction of aryl aldehydes with nitromethane (or nitroethane) by refluxing for 3-10 h efficiently afforded various arylnitroalkenes 1a-1y in 85%-97% yields.
