Abstract
Established NMR criteria from ^1^H, ^13^C and 2D J‐resolved ^13^C NMR spectra, and also ^1^H{^1^H} NOE experiments, were used to determine the constitution and configuration in a series of substituted penta‐1,3‐dien‐5‐ols.

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.
Because of the upsurge of interest in polychlorobuta-1,3-diene derivatives as uncommon contaminants in underground water, seven congeners, the three pentachloro-and four tetrachloro-[(Z)-and (E)-1,1,3,4tetrachloro-, 1,1,4,4-tetrachloro-and (Z,Z)-1,2,3,4-tetrachloro]buta-1,3-dienes, were synthesized
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.
