The reactions of the same ?H-adducts with hydroxylamine unexpectedly afforded triazacyclopenta[a]indene derivatives. The crystallographic data on the three-dimensional structures of new polycyclic compounds were obtained Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Verbitskiy, E.
