## Abstract A series of aryl‐substituted enaminoketones and their thio analogues in CDCl~3~ solution and in the solid state were studied by the use of high‐resolution ^1^H and ^13^C as well as ^13^C cross polarization magic angle spinning (CP MAS) NMR spectra in combination with gauge including ato

## Abstract Four novel 3‐alkyl(aryl)‐4‐(4‐methoxycarbonylbenzylidenamino)‐4,5‐dihydro‐1__H__‐1,2,4‐triazol‐5‐ones (**2**) were synthesized by the reactions of 3‐alkyl(aryl)‐4‐amino‐4,5‐dihydro‐1__H__‐1,2,4‐triazol‐5‐ones (**1**) with methyl 4‐formylbenzoate and characterized by elemental analyses a
Selected 1,4-and 1,5-benzoheterazepinones, prepared by the Schmidt rearrangement of flavanone analogues, were converted to the corresponding thiolactam derivatives using phosphorus pentasulfide. The proton and carbon chemical shifts of the thiolactam derivatives are compared with those of their lact
