The authors report herein the synthesis of the porphyrins 5,10,15,20-tetrakis(4-carboxybiphenyl)-porphyrin (H2TCBP) and 5,10,15,20-tetrakis(4-carboxy-2,6-dimethylbiphenyl)porphyrin (H2TCDMBP) bearing di-Ph units on meso-positions, and of their cobalt and silver derivatives The silver complexes of H2TCDMBP and of H2TCPP (H2TCPP = 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin) were studied by x-ray crystallog. and their supramol. organization elucidated. Co(TCBP) was reacted with copper formate, yielding a polymeric compound that showed a catalytic activity in the benzylic amination of hydrocarbons using arylazide as aminating agent. In the experiment, the researchers used many compounds, for example, 2,5-Dibromo-1,3-dimethylbenzene (cas: 100189-84-2Reference of 100189-84-2).
2,5-Dibromo-1,3-dimethylbenzene (cas: 100189-84-2) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Reference of 100189-84-2
