## Abstract Thirty 3‐substituted‐ and 3,4‐disubstituted‐4,5‐dihydro‐1,2,4‐triazol‐5‐ones (seven being new compounds) were synthesized and their proton magnetic resonance spectra were measured in trifluoroacetic acid (TFA). The protonation shifts observed on comparison of the spectra run in DMSO‐__d
## Abstract ^1^H NMR spectra of 21 5‐substituted‐thianthreniumyl perchlorates are reported that allow chemical shift and structural assignments to be made.
## Abstract ^1^H and ^13^C NMR spectra of 22 2‐substituted 4,5‐dimethylfurans are reported. The __J__(C, H) values were used for signal assignments and for the identification of geometrical isomers of some derivatives.
