✦ Synopsis

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 in low concentration is not always preferable for the labelling of high specific activity within a limited time. The optimum conditions for the preparation of [2-73Se]-2-selenouracil of maximum specific activity were determined.

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.

Wittig reagents were successfully changed to symmetrical olefins when treated with elemental selenium. The reaction proceeds through a selenocarbonyl intermediate, which existence was confirmed by Diels-Alder reaction. Phosphonium ylides (1) have been widely utilized for the synthesis of olefins' an

## Abstract The lithiated anions of α‐amino‐substituted diphenylphosphine oxides 1, in which R can be hydrogen, aryl, alkyl and alkenyl, react with two equivalents of sulfur or selenium to form thio‐ and selenoamides, which can be isolated in good to excellent yields in most cases. The optimal reac
