Dal Monte, D. published the artcile2,1,3-Benzothia-, selena-, and oxadiazoles. III. Amine derivatives, Category: isoxazole, the publication is Bollettino Scientifico della Facolta di Chimica Industriale di Bologna (1964), 22(2), 33-40, database is CAplus.
cf. CA 61, 10573c. Uv spectra of I and II (X = O, S, and Se) were presented and discussed. The following pKa, values in H2O at 25° were calculated: I (X = S), 2.02; I (X = Se), 2.18; I (X = O), 0.78; II (X = S), 2.01; II (X = 0),0.77; the OH analogs have pKa, 7.86, 8.16, 6.83, 8.16, and 7.28, resp. I (X = O), m. 110-11°, and II (X = O), m. 127-9°, were prepared by heating 3.1 g. 4- or 5-chloro compound with 0.8 g. CuSO4 in 80 cc. 20% NH3 8 hrs. in a sealed tube at 140-50°.
Bollettino Scientifico della Facolta di Chimica Industriale di Bologna published new progress about 874-36-2. 874-36-2 belongs to isoxazole, auxiliary class Other Aromatic Heterocyclic,Amine, name is Benzo[c][1,2,5]oxadiazol-5-amine, and the molecular formula is C6H5N3O, Category: isoxazole.
