摘要

首次报道了一种硝基氮氧化物有机银衍生物，它是芳基卤化物和杂芳基卤化物交叉偶联的有效伙伴。这种新型交叉偶联方法的基础是制备了一种含有大体积n杂环碳配体SIPrAgNN的有机银试剂，以及由Pd2dba3·CHCl3和具有金刚烷样框架的膦配体MeCgPPh组成的催化体系。发现新开发的方案与各种芳基和杂芳基卤化物具有良好的相容性，从而扩大了定向合成功能化硝基氮氧化物自由基和高自旋分子的范围。

Silver Instead of Gold in Nitronyl Nitroxide Chemistry

A nitronyl nitroxide organosilver derivative─an accessible and effective partner for cross-coupling of aryl- and heteroaryl halides─is reported for the first time. The novel cross-coupling method is based on preparation of an organosilver reagent containing a bulky N-heterocyclic carbene ligand, namely, SIPrAgNN, and a catalytic system consisting of Pd₂dba₃·CHCl₃ and phosphine ligand ^MeCgPPh having an adamantane-like framework. The newly developed protocol was found to be well-compatible with various aryl- and heteroaryl halides, thus expanding the scope of directed synthesis of functionalized nitronyl nitroxide radicals and high-spin molecules.

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.
