Reactions of diazonium salts with 4-substituted phenylaminopent-3-en-2-ones produce the corresponding 4-phenylimino-3-phenylhydrazonopentan-2-ones. On the other hand, the reaction of diazonium salt with 4-amino(or 4-methylamino)pent-3-en-2-one gives a mixture of two isomers approaching the tautomeri

C and 15 N NMR data are reported for nine azoloazines. From the results obtained it is found that the 15 N chemical shifts are particularly well placed to provide reliable data on both the structures of the compounds studied and on their potential to undergo valence and prototropic tautomerism. Of p

17O, 13C and 1H NMR spectra for paraand meta-substituted 4-arylaminopent-3-en-2-ones (acyclic enaminones, 1 and 2) and 3-arylaminocyclohex-2-en-1-ones (cyclic enaminones, 3 and 4) are reported. The 17O, 13C and 1H shift values of these enaminones correlate well with and constants in the correlations

A high-yield synthesis and puriÐcation of propiolamide is described. The structure and purity of the compound were conÐrmed by 1H, 13C and 15N NMR studies. Natural abundance 13C and 15N chemical shift measurements in 3.0 M acetonitrile solutions are reported along with 1H-1H, 1H-15N and 1H-13C spin

The tetrazole-azide tautomerization of some halogen-substituted tetrazolo [1,5-a]pyridines was examined by IR spectroscopy at ambient temperature and by 1 H, 13 C and 15 N NMR spectroscopy at various temperatures. The tetrazolopyridines can exhibit equilibrium between the azide and the tetrazole for
