  Regioselective C–H Activation Preceded by C_sp²–C_sp³ Reductive Elimination from Cyclometalated Platinum(IV) Complexes

  摘要：

  Reductive elimination reactions of the cyclometalated platinum-(IV) compounds [PtMe2Cl{C6H4CH=NCH2(4-ClC6H4)}L] and [PtMe2Br{C6H4CH=NCH2(C6H5)}L] (L = SMe2, PPh3) to form C-sp3-C-sp2 bonds, followed by either exclusive C H bond activation (L = SMe2) or competition between C-sp2-H and C-sp3-H bond activation (L = PPh3), are reported. Isomerization to give endo products instead of the expected exo complex was observed for the ligand C6H4CH=NCH2(2-BrC6H5), and formation of an endo six-membered platinacycle occurs for the ligand 2,4,6-Me3C6H2CH=NCH2(2-BrC6H4).

  cyclometalated imine ligand, two methyl groups in a cis-geometrical arrangement, a halogen, and a dimethyl sulfide as ligands, [Pt(C⌒N)(CH3)2(X)(SMe2)], have been studied as a function of temperature, solvent, and electronic and steric characteristics of the phosphines and the X and C⌒N ligands. In all cases, a limiting dissociative mechanism has been found, where the dissociation of the SMe2 ligand corresponds

  在环金属化的Pt IV络合物上，膦（PMePh 2，PEtPh 2，PPh 3，P（4-MeC 6 H 4）3，P（3-MeC 6 H 4）3，PCy 3）对SMe 2的取代反应。亚胺配体，两个甲基以顺式几何结构排列，卤素和二甲基硫醚作为配体，[Pt（C⌒N）（CH 3）2（X）（SMe 2）]，已研究了膦，X和C⌒N配体的温度，溶剂以及电子和空间特性的函数。在所有情况下，都发现了限制性的解离机理，其中SMe 2配体的解离对应于速率确定步骤。形成的五配位物种表现为真正的五配位Pt IV给定化合物在稳态浓度下的给定速率常数与溶剂无关。已经确定了两个二甲基硫醚配合物和五配位中间体的衍生物的X射线晶体结构。膦配体进入的各个速率常数的差异只能作为反应率来估算。在所有情况下，均检测到磷化氢尺寸的影响，表明从五配位中间体发生了缔合步骤。所述C⌒N亚胺的性质和X配体产生在二甲基硫醚离解反应速率，其可以通
