## Abstract Solid‐state cross‐polarization magic angle spinning ^13^C, ^77^Se and ^15^N NMR spectra were recorded for 1,3‐imidazolidine‐2‐selenone, its N‐substituted derivatives and some related compounds. The spinning sideband manifold intensities were used to obtain principal values of ^13^C and

## Abstract The X‐ray crystal structure of 1__H__‐pyrazole‐3‐(__N‐tert__‐butyl)‐carboxamide was determined. In the solid state, the ^13^C and ^15^N CP/MAS NMR spectra correspond to this tautomer. In solution, both tautomers are present in a ratio that depends on the temperature (at 293 K, 90% 3‐sub

## Abstract Formation of the four title compounds has been found to be strongly dependent on substituents: 1,2,3‐Triazolium salts **6** do not arise from nitrilimines **2** that have an electron‐acceptor attached to either the __C__‐ or the __N__‐phenyl group. Likewise __tert__‐butyl and aryl isocy
