NMR spectral data are given for the A-ring in ten 4-en-3-one steroids, and the strategy of the spectral analysis is described. The data are interpreted in terms of an equilibrium between normal and inverted half-chair conformations, with the normal conformation predominant in all cases except when Z

## Abstract Adduct formations of rhodium(II) tetraacetate and tetratrifluoroacetate with some 1H‐imidazoles, oxazoles, thiazoles, 1H‐pyrazoles and isoxazole have been investigated by the use of ^1^H, ^13^C, ^15^N NMR and electronic absorption spectroscopy (VIS) in the visible range. Azoles tend to
