7119-27-9 Usage
General Description
1-Chloro-1-buten-3-one, also known as allyl chloro ketone, is an organic compound with the chemical formula C4H5ClO. It is a colorless liquid that is commonly used as a chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. 1-CHLORO-1-BUTEN-3-ONE is also used in the manufacture of flavoring agents, fragrances, and other specialty chemicals. It is a highly reactive compound that is susceptible to nucleophilic addition reactions, making it an important building block in organic synthesis. Additionally, 1-chloro-1-buten-3-one is a potentially hazardous compound and should be handled and stored with care to prevent accidental exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 7119-27-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,1 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7119-27:
(6*7)+(5*1)+(4*1)+(3*9)+(2*2)+(1*7)=89
89 % 10 = 9
So 7119-27-9 is a valid CAS Registry Number.

Synthesis of the naphthalenone, dihydroquinoline, and dihydrofuran derivatives

The reactions of enaminones with dimethyl diazomalonate were investigated in the presence of copper(II) acetylacetonate. From the reaction of (E)-3-[methyl(phenyl)amino]-1-phenylprop-2-en-1-one (6c), dimethyl 2-[methyl(phenyl)amino]-4-oxonaphthalene-1,1-(4H)-dicarboxylate, was unexpectedly obtained as the major product. Quinoline derivatives were formed as the major products in the case of N-methyl-p-anisidino and N-methyl-p-toluidino enaminones. The reactions of acetyl enaminones were also realized, and quinoline derivatives were isolated as the major products. 3H- and 5H-dihydrofurans were also formed as side products in these reactions. These results differ from those reported earlier on the reactions of tertiary enaminones with carbenes/metal carbenes.
