Amines, tert dimethylamines

It was suggested that the dimethylamine would react with epoxide and that the resulting tert-amine would catalyse epoxide homopolymerisation. LaLiberte et al. 63) found that Monuron or Diuron could react with epoxide to form an oxazolidone and dimethylamine ... 

An azophenol crown including a pyridine unit, 66, (Fig. 19) reacts with all of amines in acetonitrile to form ammonium phenolates. The absorption maxima of 66-prim, amine systems appear in a region of 574-586 nm, which is definitely distinct from those of sec. and tert. amine systems (Xmax 602 — 606 nm except for the dimethylamine system which gave 592 nm) as shown in Fig. 19. On the other hand, a dyed crown including an additional benzene unit, 65 (Fig. 19), reacts with various amines to make ammonium phenolates which show absorption maxima of nearly constant wavelength.
