摘要

Mono-deprotonation of the bis (secondary phosphine)(RP*, RP*)-and (RP*, SP*)-1, 2- phenylenebis (methylphosphine) has been achieved using potassium in liquid ammonia to give a ca. 4∶ 1 mixture of (±)-1-(dimethylphosphino)-2-(methylphosphino) benzene and 1, 2- phenylenebis (dimethylphosphine) upon addition of a solution of methyl iodide in the same solvent. This mixture has been further treated with sodium in THF followed by the addition ...
