由铂、硫、炔烃和芳烃单元组成的 π 共轭体系是通过钯催化有机二硫化物与乙炔铂的加成反应合成的。当二苯基二硫与含有扩展炔基配体反式-(R3P)2Pt(C=C-Ar-C=C-H)2的铂(II)配合物处理时，在Pd(PPh3)4催化剂存在下，在良好的条件下区域选择性合成了新的含硫铂(II)双(烯基芳基乙炔)配合物。 产量。吸收和发光光谱表明，411-415 nm 范围内的发射取决于与铂结合的乙炔配体的性质。
π‐Conjugated systems consisting of platinum, sulfur, alkyne, and arene units were synthesized by palladium‐catalyzed addition of organic disulfides to platinum acetylides. When diphenyl disulfide was treated with platinum(II) complexes containing extended alkynyl ligands,trans‐(R3P)2Pt(C≡C–Ar–C≡C–H)2, in the presence of Pd(PPh3)4catalyst, new sulfur‐containing platinum(II) bis(alkenylarylacetylide) complexes were regioselectively synthesized in good yields. The absorption and luminescence spectra indicated that the emission exhibited in the range 411–415 nm depends on the nature of the acetylide ligand bound to platinum.
