ESR studies of ω-hydroperfluoroalkyl 1-methyl-2-substituted-pyrrolyl-5-carbonyl nitroxides and dual-parameter correlation analysis of their hyperfine splitting constants was written by Zhao, Cheng-Xue;He, Hai-Ying;Qu, Yan-Ling;Jiang, Xi-Kui. And the article was included in Journal of Fluorine Chemistry in 1999.Product Details of 81698-03-5 The following contents are mentioned in the article:
Two series of title compounds [I; R = (CF2)4H, (CF2)6H; X = H, Me, Cl, cyano, MeCO, O2N, HO2C, MeS, MeO2C, Me3Si, Br, MeO], generated in the H-abstraction/spin trapping reaction of the 12 corresponding 2-substituted 1-methylpyrrolyl-5-carboxaldehydes with the H-abstracting agent R2NO• and the spin-trapping agent RNO, were studied by ESR. Correlation anal. of the aN values of I with polar and spin-delocalization substituent constants shows that aN values are mainly affected by the polar effect, but the spin-delocalization effect also exists. This study involved multiple reactions and reactants, such as 5-Formyl-1-methyl-1H-pyrrole-2-carbonitrile (cas: 81698-03-5Product Details of 81698-03-5).
5-Formyl-1-methyl-1H-pyrrole-2-carbonitrile (cas: 81698-03-5) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Product Details of 81698-03-5
