Abstract

Reaction of Se-Alkyl phosphinoselenoates with organometallics resulted in a selective attack on the selenium atom. Sequential treatment of optically active Se-benzyl t-butylphenylphosphinoselenoate with PhLi and then with electrophiles, such as alkyl halides, an alpha,beta-unsaturated ester, and chalcogen atoms, gave optically active phosphorus compounds in 5-91% yields and in high optical yields, with retention of configuration at the phosphorus atom, along with a quantitative yield of benzyl phenyl selenide.
