Treatment of 1,3- and 1,4-bis(3,6-di-tert-butyl-9H-carbazol-9-yl)benzenes with an oxidizing system of Pd(II)/Ag(I) has been found to induce double intramol. C-H/C-H coupling to give the corresponding highly π-extended polycyclic compds I (X = CH, N), II and III. In contrast, a singly cyclized product IV in a different manner has been isolated from the reaction of 1,2-bis(3,6-di-tert-butyl-9H-carbazol-9-yl)benzene. Cardinal optoelectronic properties of the products have also been estimated2,6-Dibromopyridine(cas: 626-05-1Category: pyridine-derivatives) was used in this study.
2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. Category: pyridine-derivatives
