资源简介：
An efficient and highly regioselective synthesis of 1-allenyl-5-aryl-1,2,3-triazoles from 1-sulfonyl-4-aryl-1,2,3-triazoles is disclosed. 1-Sulfonyl-4-aryl-1,2,3-triazoles reacted with propargylic alcohols in the presence of trifluoroboron etherate to furnish 1-allenyl-5-aryl-1,2,3-triazoles. When secondary alcohols were used as substrate, the outcome of the reaction was 1-alkyl-5-aryl-1,2,3-triazoles.
