Abstract
The templating effects of strongly coordinating ions like Co(II), Cu(II), and Zn(II) can dramatically improve the yields of phthalocyanine synthesis. The main problem with this approach is the lack of reported conditions for the subsequent removal of such ions to generate metal-free phthalocyanines. During our synthesis of guanidine-containing phthalocyanines we discovered a new demetallation reaction that, to the best of our knowledge, provides the first examples of Zn(II) removal without destroying the phthalocyanine itself.
