苯基(三甲基甲硅烷基炔基)碘(III)三氟甲磺酸酯与Pt-II(O2CAr)(NCN) (Ar = Ph, 4-三氟甲基苯基(Ar-F); NCN = [C6H3(CH2NMe2)(2)-2,6])在环境温度下反应，得到Pt-IV(O2CAr)(OTf)溶液(相当于CSiMe(3))(NCN) [Ar=Ph(1a)； Ar=Ar-F(1b)]。将碘化钠 (NaI) 添加到 1 中可分离出 Pt-IV(O2CAr)I（相当于 CSiMe(3)）(NCN) [Ar = Ph (2a)； Ar = Ar-F (2b)]，产率 >90%。在这些炔基(钳)铂(IV)络合物的第一个实例中，钳基作为mer-[NCN](-)三齿供体存在，并且炔基位于钳碳供体的顺式，并且三氟甲磺酸酯(1a，1b)和碘化物基团(2a，2b)位于钳碳的反式； 2b 的 X 射线结构分析已完成。 (C) 2004 Elsevier B.V. 保留所有权利。
Reaction of phenyl(trimethylsilylalkynyl)iodine(III) triflate with Pt-II(O2CAr)(NCN) (Ar = Ph, 4-trifluoromethylphenyl (Ar-F); NCN = [C6H3(CH2NMe2)(2)-2,6]) at ambient temperature gives solutions of Pt-IV(O2CAr)(OTf)(Cequivalent toCSiMe(3))(NCN) [Ar = Ph (1a); Ar = Ar-F (1b)]. Addition of sodium iodide (NaI) to 1 results in the isolation of Pt-IV(O2CAr)I(Cequivalent toCSiMe(3))(NCN) [Ar = Ph (2a); Ar = Ar-F (2b)] in >90% yields. In these first examples of alkynyl(pincer)platinum(IV) complexes, the pincer group is present as a mer-[NCN](-) tridentate donor and the alkynyl group is located cis to the pincer carbon donor, and the triflate (1a, 1b) and iodide groups (2a, 2b) are located trans to the pincer carbon; an X-ray structural analysis has been completed for 2b.
