In view of possible solid-state polymerizations of crystalline stacked 'push-pull'-acetylenes 1. a series of compounds 1 has been synthesized (Scheme 3), and the results of,X-ray analyses of 'push-pull'-acetylenes Id,e,f are discussed. Of these three compounds, methyl 2-morpholinoacetylene carboxylate (Id) is by far the best candidate giving crystals with nicely stacked molecules (Fig. 3). Even in this case, however, stacking parameters d= 4,12 Angstrom and alpha = 31,6 degrees are too large for allowing solid-state polymerizations.

Simple and direct nucleophilic addition of secondaryamines, including imidazole, to 1,2,3-triazine under mild reaction conditions (THF, 25–65 °C, 12–48 h), requiring no additives, cleanly provides β-aminoenals 4 in good yields (21 examples, 31–79%). The reaction proceeds by amine nucleophilic addition to C4 of the 1,2,3-triazine, in situ loss of N2, and subsequent imine hydrolysis to provide 4.
