We recently reported a preliminary account of our efforts to develop novel diarylamine radical-trapping antioxidants wherein we demonstrated that the incorporation of ring nitrogens into diphenylamines affords compounds which display a compromise between H-atom transfer reactivity to peroxyl radicals and stability to one-electron oxidation Herein we provide the details of the synthetic efforts associated with that report, which have been substantially expanded to produce a library of substituted heterocyclic diarylamines that we have used to provide further insight into the structure-reactivity relationships of these compounds as antioxidants. The diarylamines were prepared in short, modular sequences from 2-aminopyridine and 2-aminopyrimidine wherein aminations of intermediate pyri(mi)dyl bromides and then Pd-catalyzed cross-coupling reactions of the amines and precursor bromides were the key steps to yield the diarylamines. The cross-coupling reactions were found to proceed best with Pd(η3-1-PhC3H4)(η5-C5H5) as precatalyst, which gave higher yields than the conventional Pd source, Pd2(dba)3. This study involved multiple reactions and reactants, such as N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2Related Products of 562085-85-2).
N-(4-Methoxyphenyl)pyridin-3-amine (cas: 562085-85-2) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 562085-85-2
