An efficient method for formal Markownikoff hydroamination/hydroarylation and double hydroamination of terminal alkynes has been developed. For example, treatment of terminal alkynes with amino-aromatics or diamines in the presence of 2-5 mol-% of Ph 3 PAuNTf 2 in toluene at 100 °C gave the corresponding products in excellent yields. The method was shown to be applicable to a broad range of substrates
已经开发了一种用于正式 Markownikoff 加氢胺化/加氢芳基化和末端炔烃双加氢胺化的有效方法。例如,在 2-5 mol-% Ph 3 PAuNTf 2 的甲苯溶液存在下,在 100 °C 下,用氨基芳烃或二胺处理末端炔烃,以优异的产率得到相应的产物。该方法被证明适用于广泛的底物,更重要的是,与我们之前报道的方法不同,炔烃中的羟基不是必需的。还讨论了反应机理。
