Effect of Substituents on the Nickel-Induced Contact Shifts in Aromatic Amines. Comparison with Spin Delocalization in Phenyl, Benzyl, and Related Radicals
The effect of substituents on the Ni(acac)2-induced proton and carbon NMR contact shifts has been studied in a series of anilines, pyridines, and heterocycles.It is found that substituents have little effect on the shifts unless bonded direcly to nitrogen or separated from it by just one atom.INDO calculations on 2-substituted phenyl radicals suggests that the singly occupied orbital is bent slightly away from the substituent, and the ESR hfcs’s as well as the nickel-induced shifts reflect this distortion.It is concluded that the specifity of Ni(acac)2 for the nitrogen lone pair, the relative constancy of its induced shifts, and their ready interpretation make this a useful NMR shift reagent for amines.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. 288-16-4, In my other articles, you can also check out more blogs about 288-16-4
