Sharma, Pawan K.; Kumar, Rajiv; Ram, Sita; Chandak, Navneet published the artcile< Deadly KCN and pricey metal free track for accessing β-ketonitriles employing mild reaction conditions>, Computed Properties of 21667-62-9 , the main research area is ketonitrile preparation green chem one pot.
A one pot synthesis of β-ketonitriles RC(O)CH2CN (R = 4-bromophenyl, 3,4-dimethoxyphenyl, naphth-1-yl, etc.) and I from readily accessible 3-chloropropenals RCH(Cl)=CHCHO and 3-chloro-3-(5-methyl-1-phenyl-1H-1,2,3-triazol-4-yl)prop-2-enal using economically benign iodine, aqueous ammonia and sodium hydroxide solution, employing mild reaction conditions have been described. This report presents a convenient, inexpensive, highly toxic-matter-free and eco-friendly approach for the product synthesis.
Synthetic Communications published new progress about Green chemistry. 21667-62-9 belongs to class nitriles-buliding-blocks, and the molecular formula is C9H6ClNO, Computed Properties of 21667-62-9 .
