N 89 Novel bis[(1,2,3-triazolyl)methyl]carborane derivatives via regiospecific copper-catalyzed 1,3-dipolar cycloaddition / V. A. Ol'shevskaya, E. V. Verbitskiy, G. L. Rusinov, V. N. Charushin, Evamarie Hey-Hawkins // Polyhedron. - 2012. - Vol.42, №1. - С. 302-306 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CARBORANES -- CARBABORANES -- TRIFLATES Аннотация: 1,2-Bis(azidomethyl)-о-carborane and 1,7-bis(azidomethyl)-m-carborane, prepared from the corresponding carboranylmethyl triflates and sodium azide, were conveniently functionalized by azide–alkyne cycloaddition affording novel bis[(1,2,3-triazolyl)methyl]carborane derivatives. Regiospecificity of this process was achieved by employing copper(II) acetate hydrate. Reaction of bis[(1,2,3-triazolyl)methyl]carborane derivatives with MeI yielded 3-methyl-1,2,3-triazolium carborane salts \\\\Expert2\\nbo\\Polyhedron\\2012. v.42. p.302.pdf |
