我们开发了一种合成方法来构建一系列新的含硒反式铂(II)-双(烯基芳基炔基)络合物，其通式为反式-[(PR3)2Pt{C≡C-Ar-C(SePh)=CH(SePh)}2]（R = 乙基、苯基，Ar = 亚苯基、联亚苯基），具有两个苯基硒基 每个烯基主链上的部分。反式铂(II)-双(炔基芳基炔基)络合物的二末端炔基配体与略超过两当量的二苯基二硒化物在氯仿中的反应，在辐射下很容易得到反式铂(II)络合物2，产率良好至优异，具有良好的区域选择性。与铂(II)配合物1的吸收带相比，发现铂(II)配合物2的最低能量吸收带位置发生红移。
A synthetic method has been developed to construct a new series of selenium‐containingtrans‐platinum(II)–bis(alkenylarylalkynyl) complexes with general formulatrans‐[(PR3)2Pt{C≡C–Ar–C(SePh)=CH(SePh)}2] (R = ethyl, phenyl, and Ar = phenylene, biphenylene), having two phenylseleno moieties on each alkenyl backbone. Reaction of the diterminal alkynyl ligand oftrans‐platinum(II)–bis(alkynylarylalkynyl) complex1with an amount slightly in excess of two equivalents of diphenyl diselenide in chloroform readily affordstrans‐platinum(II) complex2upon irradiation, in good to excellent yields with good regioselectivity. As compared to the absorption band of platinum(II) complexes1, it was found that the position of the lowest energy absorption bands of platinum(II) complexes2are redshifted.
