A convenient procedure has been developed for direct cyanation of 1,2,4-triazine 4-oxides with acetone cyanohydrin in the presence of triethylamine. The cyano group in the resulting 5-cyano-1,2,4-triazines is readily replaced by reactions with various aliphatic alcohols and amines Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Kozhevnikov, D.
