SYNTHESIS OF OPTICALLY-ACTIVE PHOSPHORUS-COMPOUNDS VIA METAL PHOSPHINITES GENERATED BY REACTION OF OPTICALLY-ACTIVE SELENOPHOSPHINATES WITHPHENYLLITHIUM

Sequential treatment of optically active Se-benzyl t-butylphenylseleno phosphinate with PhLi and then with electrophiles such as alkyl halide s and elemental selenium gave optically active phosphorus compounds in good chemical and optical yields with a retention of configuration at phosphorus atom, together with benzyl phenyl selenide.
