reactions of electron-poor alkynes are still a challenging process. A straightforward synthesis of phosphorus-based heterocycles, namely, 2-phenyl 1H-isophosphinoline 2-oxides 1, is reported. The reaction used PPh3AuCl precatalyst in combination with triflic acid under microwave activation and afforded isophosphinoline 2-oxides 1 in moderate to quantitative yields through a fully regioselective 6-endo-dig hydroarylation
缺电子炔烃的金(I)催化反应仍然是一个具有挑战性的过程。报道了一种直接合成基于磷的杂环,即 2-苯基 1 H-异膦啉 2-氧化物1。该反应在微波活化下使用 PPh 3 AuCl 预催化剂与三氟甲磺酸结合,并通过完全区域选择性的 6-endo-dig 加氢芳基化环化以中等至定量的产率提供异膦啉 2-氧化物1,为有效合成磷杂环铺平了道路。
