Popis:	‘tert-Amino Effect’ on Acidic Treatment of (Pyrrolidin-l-yl)azadienes The behaviour of 4-morpholino- and 4-(pyrrolidin-l-yl)-2-aza-1. 3-diene-l, l-dicarbonitriles 3, and 4 and 10, respectively, in acidic medium is described. The former gives with HBr/AcOH 3-bromopyrazine-2-carbonitrile 6. On the other hand, pyrrolidin-1-yl derivatives 4 and 10 furnish, by a [1, 5]-H shift, pyrrolo[l, 2]pyrazine structures 5 and 11, respectively.
