The synthesis of the two cycloplatinated(IV) complexes [PtMe(OAc)₂(C^∧N)(H₂O)] (C^∧N = 2-phenylpyridinate (2a), benzo[h]quinolate, 2b) by reaction of [PtMe(C^∧N)(SMe₂)] with PhI(OAc)₂ is described. Complexes 2 undergo carbon–oxygen bond forming reductive elimination instead of C–C reductive elimination to produce MeOAc as protected methanol. The kinetics and mechanism of both Pt–O bond formation and C–O reductive elimination have been experimentally and theoretically investigated. The results suggest that formation of methyl acetate proceeds via nucleophilic attack of the dissociated acetate ligand at the methyl group carbon in a cationic five-coordinate intermediate cycloplatinated(IV) complex.

碳氧键从环铂（IV）配合物中形成还原性消除

所述两个环铂（IV）配合物的合成[PTME（OAC）₂（C ^∧ N）（H ₂ O）]（C ^∧ N = 2-phenylpyridinate（2A），苯并[ ħ ]喹啉，2B通过的反应） [PTME（C ^∧ N）（SME ₂）]用岛（OAC）₂进行说明。配合物2经历碳-氧键形成还原消除，而不是C-C还原消除，生成MeOAc作为受保护的甲醇。对Pt–O键形成和C–O还原消除的动力学和机理进行了实验和理论研究。结果表明，乙酸甲酯的形成是通过离解的乙酸酯配体在阳离子五配位中间体环铂（IV）配合物的甲基碳上的亲核攻击而进行的。
