An efficient and green one-pot synthesis of 1,4-disubstituted
1,2,3-triazoles from aryl iodides and alkyl chlorides, sodium azide,
and terminal alkynes catalyzed by copper(I) and amino acid ionic
liquid (AAIL) in [BMIM]BF4 was developed.
The reactions proceeded smoothly to generate the corresponding products
in high yields. In addition, CuI, AAIL, and [BMIM]BF4 could
be recovered for six consecutive trials without significant loss
of activity.
