Abstract

The reaction of PhCHBr₂ with the cycloneophylplatinum complex [Pt(CH₂CMe₂C₆H₄)(NN)], 1, NN = 4,4’-di-t-butyl-2,2’-bipyridine (bubipy), gave the complex [PtBr₂(CH₂CMe₂C₆H₄CHPh)(NN)], 2, which is formed by formal oxidative insertion of benzylidene, PhCH, into the arylplatinum bond of 1. By monitoring the reactions by ¹H NMR spectroscopy, intermediates were detected and shown to be products of oxidative addition [PtBr(CHBrPh)(CH₂CMe₂C₆H₄CHPh)(NN)], 3, along with a side product [PtBr₂(CH₂CMe₂C₆H₄)(NN)]. The formation of 2 gives the first example of selective benzylidene insertion reactions into an aryl–platinum bond, with potential for applications in catalysis.

闪光通讯：有机铂配合物中的选择性苄基插入反应

PhCHBr2与环叶铂配合物[Pt(CH2CMe2C6H4)（NN)], 1, NN = 4,4′-二叔丁基-2,2′-联吡啶（bubipy））反应，得到配合物[PtBr2(CH2CMe2C6H4CHPh)(NN)], 2，该配合物是由苄基苯乙烯（PhCH）正式氧化插入到1的芳基铂键中形成的。通过1H NMR监测反应，检测到中间产物为氧化加成产物[PtBr(CHBrPh)(CH2CMe2C6H4CHPh)(NN)]， 3和副产物[PtBr2(CH2CMe2C6H4)(NN)]。2的形成给出了选择性苄基插入反应进入芳基-铂键的第一个例子，具有催化应用的潜力。

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
