unexpected formation of 3,3′,5,5′-tetra[(dimethylamino)methyl]-4,4′-bis(platinum halide)-benzophenone (halide = Br or Cl), referred to hereafter as the bispincer-benzophenone complex 13. This material was further characterized using X-ray crystal structure determination. The applicability of the pincer complexes in the McMurry reaction is shown to open a route towards the synthesis of tamoxifen-type derivatives
后修饰一系列NCN钳式铂(II)配合物[PtX(NCN-R-4)](NCN = [C 6 H 2(CH 2 NMe 2)2 -2,6] – –,R = C (O)H,C(O)Me和C(O)的Et),X =氯-或Br -的)对位研究了使用McMurry反应的位置。同样描述了上述两个新的[PtCl(NCN-R-4)](R = C(O)Me和C(O)Et)配合物的合成路线。系统地评估了涉及这些钳形复合物的McMurry反应的效用和局限性。预测的[PtBr(NCN-C(O)H-4)的“均偶联”反应导致意外形成3,3',5,5'-四[(二甲基氨基)甲基] -4,4 ′-双(卤化铂)-二苯甲酮(卤化物= Br或Cl),以下称为bispincer-二苯甲酮复合物13。使用X射线晶体结构测定进一步表征该材料。钳式配合物在McMurry反应中的适用性为他莫西芬型衍生物的合成开辟了一条途径,其中他莫昔芬的一个
