Abstract
Good to excellent yields of 1,4-disubstituted 1,2,3-triazoles were obtained within 2-25 min when the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction was carried out under solvent-free conditions, with [Cu(phen)(PPh(3))(2)]NO(3) (1mol%) as the catalyst.
摘要
在无溶剂条件下，当使用[Cu(phen)(PPh(3))(2)]NO(3)（1mol%）作为催化剂时，铜（I）催化的叠氮化物-炔烃环加成（CuAAC）反应在 2-25 分钟内可得到 1,4-二取代 1,2,3-三唑的高产率，达到 1,4-二取代 1,2,3-三唑。
