  摘要：

  总共合成了48种新的双（三苯基膦）（肉桂酸酯）铂（0）配合物，以研究电子和空间位阻对其作为受抑制前催化剂的行为的影响，并将其与1 H，13 C，19 F，31 P和195 Pt NMR光谱，IR光谱和X射线结构特性（包括9个X射线结构）。事实证明，苯基4位上的取代基是控制烯烃配体电子特性以及控制金属-配体键强度的重要部分。反应性和NMR光谱数据与该取代基的Hammett参数相关：尤其是偶联常数2 J PP和1 J PPt。配合物的反应性是通过三苯膦的NMR滴定法（1 H NMR；触发配体取代）以及与二苯基硅烷的反应（1 H和29 Si NMR；触发氧化加成）确定的。所确定的平衡与烯烃的电子密度相关。作为一个典型的例子，可以从配合物的NMR 2 J PP偶合常数间接预测反应性，这也可以从相关的Pd配合物中发现。
