The disproportionation of 2 equiv of (L)2Pd(CH3)(X) to form 1 equiv of (L)2Pd(CH3)2 and 1 equiv of (L)2Pd(X)2 could serve as a key step in the catalytic oxidative oligomerization of methane. The thermodynamics associated with this transformation have been evaluated as a function of the supporting ligands L and X using DFT calculations. With these calculations as a guide, we demonstrate the first experimental
2当量的歧化(L)2加入Pd(CH 3)(X)以形成1个当量的(L)2加入Pd(CH 3)2(L)和1当量2的Pd(X)2可作为
甲烷催化氧化低聚的关键步骤。使用DFT计算,已评估了与该转变有关的热力学与支撑
配体L和X的关系。以这些计算为指导,我们展示了使用(t Bu-bpy)Pd(CH 3)(CH 2)的Pd II单甲基配合物歧化生成Pd II二甲基物种的第一个实验示例。COCH 3)(吨卜联
