以邻膦苯硼酸盐与二甲基锌为原料，通过硼锌双金属化反应，成功合成了邻膦苯二锌衍生物。邻位PR2取代基的存在显著加速了二芳基锌的金属化反应。这些有机锌化合物作为可分离的苯系p锌螯合体，提供p锌钯和钌配合物与西格玛接受锌金属配体。
Bis(o-phosphinophenyl)zinc derivatives were successfully synthesized by the reaction of o-phosphinophenylboronates with dimethylzinc via boron-zinc double transmetallation. The transmetallation was significantly accelerated by the presence of the ortho PR2 substituent to give diarylzinc selectively. These organozinc compounds act as isolable phenylene-tethered PZnP-pincer ligands, affording PZnP-palladium and ruthenium complexes with a sigma-accepting Zn-metalloligand.
