本文报道了在锂醇盐催化下，3，6-二烷氧基-4，5-二氯邻苯二甲腈、1，4-二烷氧基萘-2，3-二甲腈和3，6-二烷氧基酞腈的环状四聚反应，得到相应的无金属八烷氧基八氯酞菁、八烷氧基萘酞菁和八烷氧基酞菁。在前两个系列的前体的环化期间发生意外的反式烷氧基化反应。不含金属的酞菁和萘酞菁已经被转化成含有各种金属离子的衍生物。在甲苯溶液中，化合物在739-862 nm范围内有Q带吸收。报道了所选实例的荧光光谱。一些化合物的溶解度已经在液晶材料的制剂中测量。
The lithium alkoxide-catalysed cyclic tetramerisation of various 3,6-dialkoxy-4,5-dichlorophthalonitriles, 1,4-dialkoxynaphthalene-2, 3-dicarbonitriles and 3,6-dialkoxyphthalonitriles to give the corresponding metal-free octa-alkoxyoctachlorophthalocyanines, octa-alkoxynaphthalocyanines and octa-alkoxyphthalocyanines is described. An unexpected trans-alkoxylation reaction occurs during the cyclisation of the first two series of precursors. Metal-free phthalocyanines and naphthalocyanines have been converted into derivatives containing various metal ions. Compounds show Q-band absorption in the region 739–862 nm in toluene solution. The fluorescence spectra of selected examples are reported. The solubility of some of the compounds has been measured in a formulation of liquid crystal materials.
