Abstract

The reaction of Li metal with alkyldiphenylphosphines generates the alkylphenylphosphide anions, which can undergo subsequent reactions with alkyl halides to give chiral phosphines (RR'R'P). The 31P nmr chemical shifts have been measured for these phosphines, and show greater deviations from the values predicted by the first order additivity model than do those of more symmetrical phosphines (ie, R3P and R2R'P). The ...
