Gold(I)-catalyzed cyclization of o-alkenyl-o’-alkynylbiaryls in the presence of external or internal nucleophiles provides a straightforward access to phenanthrene-based polycycles, which are of considerable interest in materials science. Thus, their reactions with alcohols yield functionalized dihydrophenanthrenes, in a process that can also be carried out intramolecularly, to provide phenanthrene-derived
在外部或内部亲核试剂存在下,金 (I) 催化的o -烯基- o' -炔基联芳基环化提供了一种直接获得基于菲的多环化合物的途径,这在材料科学中具有相当大的意义。因此,它们与醇的反应产生功能化的二氢菲,该过程也可以在分子内进行,以提供菲衍生的杂多环化合物。此外,苯并[ b ]苯并[b]联苯可以由o-甲氧基乙烯基-o'-炔基联芳基合成,在其中三键上的(杂)芳基取代基充当内部亲核试剂的反应中。
