Abstract
It was shown that cyanamide can successfully be used in reactions of nucleo philic substitution of hydrogen with 1,2,4-triazin-4-oxides in the presence of a base to give 5-cyanoimino-1,2,4-triazines. It was found by C-13 NMR s pectroscopy that these compounds and their alkylation products at the cycli c nitrogen atom exist in the form of 5-cyanoimino-2,5-dihydro-1,2,4-triazin es.
