with [Bu4N]OH and MCl2·nH2O (M = Cu, Ni; n = 2, 6) gave conveniently mononuclear [Bu4N]2[M(3,4-bopbNPrH)] (M-9b, M = Cu, Ni). After thus optimizing reaction conditions, for the synthesis of higher-branched bis(oxamato) type complexes the (polyamido)amines 5c (enIIH2), 5d (denIIIH3), 5e (denVH5) and 5f (denXH10), possessing two, three, five or ten terminal amino groups, were reacted with appropriate equiv
用[Bu 4 N] OH和MCl 2 · n H 2 O(M = Cu )连续处理3,4-双(草酸酯)亚苯基苯甲酸的二乙酯(3,4-bopbH 2 Et 2 OH; 1),Ni;n = 2,6),提取到CH 2 Cl 2中后,得到双核络合物[Bu 4 N] 4 [M(3,4-bopbO)} 2 CH 2 ](M-3,M = Cu ,Ni)作为新型对称的亚甲基二酯。相反,随后将[Bu 4 N] OH和无水NiCl 2添加到1而是提供了非常吸湿的[Bu 4 N] 3 [Ni(3,4-bopbO)](4)。为了验证反应条件,以使相应的羧酰胺达到1 –作为合成较高级树枝状聚合物的关键步骤–研究表明1与RNH 2(R = Me(5a),Pr(5b))反应生成[RNH 3 ] [tdqc](R = Me(6a),Pr(6b); tdqc = 1,2,3,4-四氢-2,3-二氧代-6-喹喔啉羧酸盐)。或者,如果先将1转换为3
