The reaction of nitrilimines 2a.b with hydrazones of aliphatic ketones 3 (RHNN=CR'R) led to the formation of the cyclocondensation products 1,2,4,5-tetrazines 4a-g when R = CH3, and to acyclic electrophilic addition products 5a-g when R = H, rather than the cyclocondensation tetrazines products 8.
当 R = CH3 时,腈亚胺 2a.b 与脂肪族酮 3 腙 (RHNN=CR'R) 的反应导致环缩合产物 1,2,4,5-四嗪 4a-g 的形成,以及非环状亲电加成当 R = H 时产物 5a-g,而不是环缩合四嗪产物 8。
