摘要：
The reaction of nitrilimines 2a,b with hydrazones of aliphatic ketones 3 (RHNN==(CRR2)-R-1) 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.
