Заглавие : A convenient method for the preparation of mono- and bis-substituted photochromic bis(benzothienyl)perfluorocyclopentenes via regioselective Friedel–Crafts acylation Место публикации : Tetrahedron Letters. - 2012. - Vol.53, №44. - С. 5948-5951 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Ключевые слова (''Своб.индексиров.''): regioselective friedel–crafts acylation--photochrome--benzofurans Аннотация: The regioselective Friedel–Crafts acylation of 1,2-bis(2-methylbenzo[b]thien-3-yl)hexafluorocyclopentene was developed. Depending on the reaction conditions, mono- or bis(bromoacetyl) derivatives are formed as single products in good yields. Further heterocyclizations involving α-bromoketone moieties gave a series of new photochromic compounds Доп.точки доступа: Bogatishcheva, N. S.; Yarovenko, V. N.; Levchenko, K.S.; Kobeleva, O.
