Hattori, Yohei; Nishikawa, Michihiro; Kusamoto, Tetsuro; Kume, Shoko; Nishihara, Hiroshi published the artcile< Steric interference on the redox-conjugated pyrimidine ring rotation of mono- and dinuclear copper complexes with (4-methyl-2-pyrimidinyl)imine ligands>, Application of C6H11NO2, the main research area is copper phenanthroline methylpyrimidinylmethylene benzeneamine complex preparation; electrochem copper phenanthroline methylpyrimidinylmethylene benzeneamine complex; crystal structure copper phenanthroline methylpyrimidinylmethylene benzeneamine complex.
A mononuclear copper(I) complex with N-[(4-methyl-2-pyrimidinyl)methylene]-p-toluidine (1·BF4; [(Phen-anth2)Cu(L1)]·BF4) and a dinuclear copper(I) complex with N,N’-bis[(4-methyl-2-pyrimidinyl)-methylene]-p-phenylenediamine (2·(BF4)2; [(Phen-anth2)2Cu2(μ-L2)]·(BF4)2) (where Phen-anth2 = dianthracenylphenathroline, L1 = N-[(4-methyl-2-pyrimidinyl)methylene]-p-toluide and L2 = N,N’-bis[(4-methyl-2-pyrimidinyl)methylene]-p-phenylenediamine) were synthesized as BF4- salts to evaluate the influence of the imine moiety on the pyrimidine ring rotation isomerism. 1·BF4 existed in solution as a mixture of two isomers; 2·(BF4)2 was present as a mixture of three isomers. The redox potentials of the copper centers were changed by pyrimidine ring rotation. Comparison of 1+ and 22+ indicated that increasing the steric congestion around the copper center increased the o/i isomer ratio; the redox potentials of both the o- and i-isomers shifted in the pos. direction, and the CuII/I redox reaction became slower.
