2]paracyclophane (2). An improved synthesis of 2 from [2.2]paracyclophane also is reported. BPPc (3a): monoclinic, P2(1)/c, a = 8.2238(11) A, b = 15.336(2) A, c = 8.4532(11) A, beta = 98.578(3) degrees, V = 1054.2(2) A(3), Z = 2. To investigate the binding properties of the bis-diimino[2.2]paracyclophane ligands, binuclear rhenium(I) tricarbonyl chloride complexes [Re(CO)(3)Cl](2)(micro-BPPc) (5a) and [Re(CO)(3)Cl](2)(micro-BmPPc)
两个伪对位取代的双-二亚氨基[2.2]对环环糊精配体(4,16-双(吡啶并亚吡啶胺)-[2.2]对环环糊精(BPPc)和4,16-双(甲基-吡啶并亚胺基)-[2.2]对环环糊精(BmPPc))通过适当的吡啶啉亚胺与4,16-二氨基-[2.2]对环环烷(2)的缩合反应制备了二甲基吡啶。还报道了由[2.2]对环环烷改进的2的合成。BPPc(3a):单斜晶,P2(1)/ c,a = 8.2238(11)A,b = 15.336(2)A,c = 8.4532(11)A,beta = 98.578(3)度,V = 1054.2( 2)A(3),Z =2。要研究双二亚氨基[2.2]对环环烷配体的结合特性,双核rh(I)三羰基氯配合物[Re(CO)(3)Cl](2)(micro制备了-BPPc)(5a)和[Re(CO)(3)Cl](2)(micro-BmPPc)(5b),并通过红外光谱,(1)H NMR
