Abstract


The synthesis of 1,4-disubstituted-1,2,3-triazoles from alkylazides and terminal alkynes at room temperature and under microwaveheating was attained using Cu(I), generated in-situ fromcopper(II) sulfate and phenylboronic acid, as catalyst. Twelve newtriazoles were obtained in moderate to good yields (53-98%), and theproducts were obtained by crystallization from the mixture reactionwithout further purification
