Jordan 1,3,5-Tris(5-substituted-1,3,4-oxadiazol-2-yl)benzenes were prepared by the dehydration of the corresponding hydrazides. The structures of these compounds were elucidated by IR, 1H and 13C NMR spectroscopy.

✦ Synopsis
A series of 14 3-substituted 4-oxoquinolones with or without a substituent (methyl, ethyl) in position 1 were prepared. Literature and measured data were used to study the inÑuence of the substituent on the shifts of carbon atoms of these compounds, which are model compounds for antibacterial drugs of the nalidixic acid type.

A set of 3-alkylaminoacroleins (R1NHCHxCHCHxO, R1 \ alkyl) were studied by 13C and 1H NMR spectroscopy in solutions of di †erent solvents and, for the simplest representative of the series, 3methylaminoacrolein, at di †erent temperatures. The equilibrium solutions of these compounds consists of mixt
1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.
The complete assignment of the 1H, 13C and 19F NMR spectra of eight Ñuoro-substituted 3H-naphthopyrans was achieved by the concerted application of homonuclear (1HÈ1H) and heteronuclear (13CÈ1H and 19FÈ1H) correlations.
