73Se labelled 2-selenouracil was prepared by the isotope exchange reaction method. It has been well known that in order to prepare labelled compounds in high specific activity by exchange reaction, the substrate compounds have to be used in small quantities. For 2-selenouracil, however, the reaction
## Abstract ^77^Se NMR chemical shifts and ^1^__J__(SeC) coupling constants were measured for nine organic selenium compounds: 4,5,6,7‐tetrahydro‐,4′,4′,6,6‐tetramethylspiro[1,3‐benzoxaselenole‐2,1′‐cyclohexane]‐2′,4,6′‐trione and closely related derivatives, bis(2‐hydroxy‐4,4,6,6‐tetramethyl‐3‐oxo
