The efficient hydrohydrazidation of terminal (6a–r, 18 examples, 0.1–0.2 mol % [(NHC)Au(NTf2)], T = 60 °C) and internal alkynes (7a–j, 10 examples, 0.2–0.5 mol % [(NHC)Au(NTf2)], T = 60–80 °C) utilizing a complex with a sterically demanding bispentiptycenyl-substituted NHC ligand and the benign reaction solvent anisole, is reported.
末端(6a – r,18例,0.1–0.2 mol%[(NHC)Au(NTf 2)],T = 60°C)和内部炔烃的有效氢氢化反应(7a – j,10例,0.2–0.5 mol报道了[%((NHC)Au(NTf 2)],T = 60–80°C),该化合物与具有空间要求的双戊二烯基取代的NHC配体和良性反应溶剂苯甲醚形成复合物。
