Nicholas reactions of the p-phenyl linked bis(propargyl acetate) complex (3a) with electron rich arenes give cyclophanetetrayne complexes (5). The use of bis(propargyl ether) complex (8) with (3a) allows formation of a mixed cyclophanetetrayne complex (9), and in addition gives retro-Nicholas/intramolecular Nicholas reaction product (2).
尼古拉斯反应中,p-苯基连接的双(丙炔基醋酸酯)络合物(3a)与富电子的芳烃反应生成环烷酮四炔络合物(5)。使用双(丙炔醚)络合物(8)与(3a)可以形成混合环烷酮四炔络合物(9),并且还生成逆尼古拉斯/分子内尼古拉斯反应产物(2)。
