[(bpy)(4)Ru(2)[mu(2)-N,N':N",N"'-[[4,9-(NH(2))(2)-3,10-(NH)(2)]C(20)H(8)]]](PF(6))(4) (9), the redox properties of which were studied by cyclic voltammetry. The difference in the potentials of the two one-electron redox steps (225 mV) indicates strong coupling of the metal centers through the 4,9-diaminoperylenquinone-3,10-dimine bridging ligand and corresponds to a comproportionation constant K(c) of 6.3 x 10(3)
1,8-二氨基萘的三甲基甲硅烷基化得到1,8-双(三甲基甲硅烷基氨基)萘(1 a),然后将其与两个摩尔当量的正丁基锂锂化,得到三(thf)溶剂化的二酰胺二锂[1,8 -[(Me(3)SiN)Li(thf)](2)C(10)H(6)](thf)(2 a)。通过先前表征的混合金属酰胺[1-[(Me(3)SiN)Li(thf)(2)]-8-[(Me(3)),分两步与TlCl进行金属交换SiN)Tl] C(10)H(6)],得到二th二酰胺[1,8-[(Me(3)SiN)Tl](2)C(10)H(6)](3 a) 。加热3a,干净地得到4,9-双(三甲基甲硅烷基氨基)per醌-3,10-双(三甲基甲硅烷基limine)(4a)和1a的1:1混合物。通过这种途径,以高收率获得了一系列完整的4a的甲硅烷基化同源物,而事实证明,该方法对于合成烷基取代的类似物是无效的。用钠汞齐还原化合物4a及其叔丁基二甲
