This article describes the high-yielding and selective oxidatively induced formation of ethane from mono-methyl palladiumcomplexes. Mechanistic details of this reaction have been explored via both experiment and computation. On the basis of these studies, a mechanism involving methyl group transmetalation between Pd(II) and Pd(IV) interediates is proposed.

This communication describes studies of oxidatively induced C-C bond-forming reductive elimination from ((t)Bu(2)bpy)Pd(II)(Me)(2). With the outer-sphere oxidant ferrocenium, the data are consistent with a mechanism involving Pd(III) and Pd(IV) intermediates, with C-C bond formation occurring from the latter. The reaction with Ag(+) appears to proceed via a Pd-Ag(+) adduct, which then undergoes inner
本通讯描述了从 ((t)Bu(2)bpy)Pd(II)(Me)(2) 氧化诱导 CC 键形成还原消除的研究。对于外球氧化剂二茂铁,数据与涉及 Pd(III) 和 Pd(IV) 中间体的机制一致,后者形成 CC 键。与 Ag(+) 的反应似乎通过 Pd-Ag(+) 加合物进行,然后进行内球电子转移以生成 Pd(III)。相比之下,较慢的苯醌反应通过不同的途径形成乙烷,该途径不涉及甲基乱序并生成 Pd(0) 产物。
