the absence of a sacrificial oxidant is described. Vital to the success of this method is the implementation of a bimetallic catalyst bearing a bis(phosphino)amine ligand. A mechanistic hypothesis is presented, and observable transmetalation, CBr oxidative addition, and CC reductive elimination in a model gold complex are shown. We expect that this method will serve as a platform for the development
描述了在没有牺牲氧化剂的情况下由金催化的sp 3 –sp 2 C C 交叉偶联反应。该方法成功的关键是采用带有双(膦基)胺配体的双金属催化剂。提出了一个机制假设,并显示了模型金配合物中可观察到的金属转移、C Br 氧化加成和 C C 还原消除。我们预计这种方法将成为开发涉及氧化还原活性金催化剂的新型转化的平台。

Rhodium- and Iridium-CatalyzedAllylation of Electron-Rich Arenes with Allyl Tosylate
The allylation of electron-rich arenes with allyl tosylate proceeded at 0 °C in the presence of [Rh(nbd)(CH3CN)2]PF6. Various oxygenated arenes were allylated with high para-selectivity in almost all cases. Especially in the reaction of anisoles, the tendency was remarkable.
