A comparison has been carried out of the reactivity of 5-trifluoromethylpyrazolyl-substituted 1,2,4,5-tetrazines and their unfluorinated analogs in nucleophilic substitution and [4 + 2] cycloaddition reactions Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Tolshchina, S.
