Abstract

Fluoroalkylsulfonyl azides were successfully employed as an efficient reacting partner in copper(I)-catalyzed three-component couplings with terminal alkynes and amines to afford the corresponding N′-(fluoroalkylsulfonyl) amidines in good yields. Possible reaction pathways are proposed.

Key words

multicomponent reactions - fluoroalkylsulfonyl azides - 1-alkynes - amines - amidines
