2,2-Bipyridine ligands bearing functionalised aryl substituents have been prepared with the aim of subsequent functionalisation and the preparation of multinuclear metallostars. The key intermediates are compounds containing 4-methoxyphenyl substituents which may be converted to 4-hydroxyphenyl substituted ligands. Copper(I) and silver(I) complexes of 4,4′-di(methoxyphenyl)-6,6′-dimethyl-2,2′-bipyridine
为了随后的官能化和多核金属星的制备,已经制备了带有官能化的芳基取代基的2,2-联吡啶配体。关键中间体是含有4-甲氧基苯基取代基的化合物,该化合物可转化为4-羟苯基取代的配体。已经制备了4,4'-二(甲氧基苯基)-6,6'-二甲基-2,2'-联吡啶的铜(I)和银(I)配合物,并在结构上表征为具有配体4,4'-di (甲氧基苯基)-6,6'-二甲基-2,2'-联吡啶和4,4'-二(甲氧基苯基)-2,2'-联吡啶。
