Rk. Boeckman et al., New heterocyclic precursors for thermal generation of reactive, electron-rich 1,2-diaza-1 3-butadienes, ORG LETT, 3(23), 2001, pp. 3647-3650
[GRAPHICS]
The preparation and thermolysis of new stable heterocyclic precursors of 1,
2-diaza-1,3-butadienes is described. The resulting reactive diazadienes are
trapped in situ with N-phenyldiazamaleimide. The effect of precursor struc
ture on the temperature at which the diazadienes are generated is discussed
.
