An efficient and rapid procedure for ring opening of various epoxides with aromatic, aliphatic and heterocyclicamines is developed at room temperature under solvent-free conditions in the presence of (C4H12N2)2[BiCl6]Cl·H2O (1 mol %). This catalyst can be reused several times without losing of its activity.
在(C 4 H 12 N 2)2 [BiCl 6 ] Cl·H 2 O存在下,在室温下在无溶剂的条件下,开发了一种高效快速的方法,可用于芳族,脂族和杂环胺的各种环氧化物的开环。(1摩尔%)。该催化剂可以重复使用几次而不会失去其活性。
