    • The amount of benzyl azide was roughly based on the apparent success of the desilylation reaction, and varied from 0.66 to 1.0 equiv. Isolated yields are reported based on the amount of benzyl azide used; see the Experimental Section for details

    • Caution: It should be noted that Armitage has reported that the terminal triyne derived from 11d "exploded at 0 °C in the absence of air", see:;, One should, therefore, not attempt to isolate this terminal triyne neat. Although we have not experienced any problems, the terminal polyynes reported herein should all be treated as potentially explosive and handled with care
