Abstract: Abstract Peculiarities of the molecular geometry, electronic structure and spectral properties of heterocyclic subphthalocyanines analogues containing electron-deficient heterocycles have been considered using DFT and TD DFT methods. Subporphyrazine with annulated 1,2,5-selenadiazole rings was prepared and… read more here.

Abstract: A novel and efficient approach for the amine-directed dehydrogenative C(sp2)-C(sp3) coupling of arylamines with acetonitrile was reported by using FeCl2 as the catalyst. Substituted anilines, aminopyridines, naphthylamines, and some nitrogen-containing heterocyclic arylamines react with inactive… read more here.
