Formula: C6H4BrIIn 2020 ,《Synthesis, Structure, and Optical Properties of Di-m-benzihexaphyrins (1.1.0.0.0.0) and Di-m-benziheptaphyrins (1.0.1.0.0.0.0): Blackening of m-Phenylene-Linked Dicarbaporphyrinoids by Simple π-Expansion》 appeared in Journal of Organic Chemistry. The author of the article were Sulfikarali, Thondikkal; Ajay, Jayaprakash; Suresh, Cherumuttathu H.; Bijina, Padinjare V.; Gokulnath, Sabapathi. The article conveys some information:
Acid catalyzed condensation of newly prepared di-m-benzipentapyrrane with appropriate mono- and diheterocyclic dialcs. selectively produced stable di-m-benzihexaphyrins and di-m-benziheptaphyrins with only two meso-carbon bridges. Single-crystal X-ray diffraction analyses reveal planar conformation with slight distortion of bridged phenylene rings. Despite the presence of m-phenylene units interrupting the global delocalization, the presence of bithiophene unit in di-m-benziheptaphyrins 3a-b exhibit altered optical features covering the entire visible region (∼250-720 nm) exhibiting black dye property as a “”metal-free”” porphyrinoid. After reading the article, we found that the author used 1-Bromo-3-iodobenzene(cas: 591-18-4Formula: C6H4BrI)
1-Bromo-3-iodobenzene(cas: 591-18-4) has been used in the preparation of 1-(3′-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodec-1-ene and 1-(3′-bromophenyl)-3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene.Formula: C6H4BrI
