resulting from either the double arylation of the naphthalenic substrate or the formal dimerizative arylation have been prepared. For example, in the latter mode, ternaphthalene was converted into a series of linear octiarenes (counting the capping Ar). The process represents an alternative to the cross-coupling methodologies employed in related syntheses and proceeds via a selective functionalization
在线性条件下,使用高价PIFA / BF 3试剂可实现直链对和季萘与取代苯之间的直接脱氢偶联。已经制备了由萘底物的双重芳基化或形式的二聚化芳基化产生的产物。例如,在后一种模式下,将对苯二酚转化为一系列线性的辛烯(计算封端Ar)。该方法代表了相关合成中使用的交叉偶联方法的替代方法,并通过六个相对惰性的芳香族CH键的选择性官能化进行。
