Chan, Joseph Y. M. published the artcile[3 + 1] Mixed Cyclization: A Synthetic Route to Prepare Low-Symmetry Phthalocyanines, HPLC of Formula: 91-15-6, the main research area is zinc phthalocyanine nanoparticle preparation; base promoted cyclization trisphthalonitrile metal template.
A novel synthetic strategy for low-symmetry phthalocyanines was developed, which involves the base-promoted cyclization of a preconnected trisphthalonitrile and a free phthalonitrile in the presence of a metal template. By using this [3 + 1] mixed cyclization approach, a series of zinc(II) phthalocyanine derivatives were synthesized in up to 12% yields, including a very rare ABCD-type phthalocyanine and an amphiphilic ABAC-type analog that can self-assemble in aqueous media, forming stable spherical nanoparticles.
Journal of Organic Chemistry published new progress about Cyclization. 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, HPLC of Formula: 91-15-6.
