✦ Synopsis

Abstract

The ^13^C NMR chemical shifts and one‐bond carbon–hydrogen coupling constants have been obtained for the title compounds in carbon disulphide as solvent. There appears to be little solvent effect on the ^13^C chemical shifts. The results suggest the order of release of electrons into the ring is O ≫ S > Se.
