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
Reaction of tert-butylarylmethylenetriphenylphosphoranes with elemental selenium afforded the corresponding 1,2,4triselenolanes (1), 1,3-diselenetanes (4), and triphenylphosphine selenide. Triselenolanes 1 were formed from selenation of 4, which may suggest a stepwise selenation of selenoketones.
