Abstract: Title compds. (I) were manufd. by contacting unsatd. org. compds. with O2 at 250-600≦̸C in the presence of catalyst(II; A = Nb, Zr, Ti, Ta; E = hydrazinehydrate, Mo powder, W, Mg, Al, or Ni; a = 0.01-6, C = 0-0.2, e,f = 1-9; X = Number which satisfies other element's valence). Thus, passing 73:1 air-C4H10 over this catalyst at 419≦̸C gives I with conversion 75.37%.
