We found that the rearrangement of the corresponding ethoxyethy-nyl derivative using AgOTf (1 mol , alone was completed at room temperature for 0.5 h; however, that of lq with AgOTf 2 mol , alone gave 2q in less than 5% NMR yields. Thus, the trimetallic catalytic system was revealed to be highly effective for less activated alkynes. For details, see Supporting Information
