On the Reactivity of Cyanamides toward Acceptor‐Substituted 1,2,4‐Triazines N ‐substituted cyanamides 2a – d cycloadd exclusively across C‐5/N‐2 of the 1,2,4‐triazine nucleus 1 yielding the bicycle 6 as nonisolable intermediate. Elimination of trifluoroacetonitril leads to the 1,3,5‐triazines 7 as the main reaction products. Besides, the 1,2,4‐triazines 8 are formed by loss of methyl thiocyanate.
