What is ^77^Se, ^13^C and ^1^H NMR investigations on ortho ‐carbonyl benzeneselenenyl derivatives about?

## Abstract __o__‐Carbonyl benzeneselenenyl compounds with COCH~3~, CHO and COOCH~3~ as carbonyl functions and SeCl, SeBr, SeSCN, SeSeCN, SeCN and SeCH~3~ as selenium‐containing groups, have been studied by ^1^H, ^13^C and ^77^Se NMR spectroscopy. The IR CO stretching frequencies of these compounds are also reported. If the SeCH~3~ derivatives are excluded, the compounds mainly adopt a planar ‘__cis__’ conformation, due to an interaction between the CO group and the selenium atom. The range of over 800 ppm for the observed ^77^Se chemical shifts makes ^77^Se NMR spectroscopy a powerful tool for physical organic chemists.
