摘要：
A practical synthesis of symmetrical vicinal diamines with broad chemistry scope is described.The key step is the ultrasonicwave promoted tandem-reaction,two-step reaction sequence combining Mannich double condensations with benzo- triazole,glyoxal and primary or secondary amines and reduction of the bis(benzotriazole)-adducts with sodium borohydride proceeded smoothly in tetrahydrofuran in high yield at room temperature.
