The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine( cas:89972-77-0 ) is researched.Quality Control of 4-(p-Tolyl)-2,2:6,2-terpyridine.Turonek, Mary L.; Moore, Peter; Errington, William published the article 《Synthesis of the terpyridyl pendant-arm azamacrocycle 4′-(p-1,4,7-triazacyclonon-1-ylmethylphenyl)-2,2′:6′,2”-terpyridine (L) and complexes of L with copper(II) and nickel(II).

Let’s learn more about this compound (cas:89972-77-0).
The azamacrocyclic ligand 4′-(p-1,4,7-triazacyclonon-1-ylmethylphenyl)-2,2′:6′,2”-terpyridine (L) was prepared, some of the complexes it forms with hydrated Cu(II) and Ni(II) were isolated as the [PF6]- salts. X-ray crystallog. was used to determine the solid state structure of the distorted trigonal bipyramidal complex [Cu(HL)(H2O)2][PF6]3, in which the Cu(II) is coordinated to the terpyridyl group and the azamacrocycle is monoprotonated and noncoordinating. A bis(2,2′:6′,2”-terpyridine)nickel(II) complex, [Ni(H2L2)2][PF6]6 also was isolated, in which each azamacrocycle is diprotonated. Both complexes were studied by cyclic voltammetry.
