    • Although the starting acetylide complex 2 is stable to atmospheric moisture, acidic or strongly protic solvents or azides can sever the Cu-acetylide bond. The liberated Cu(I) will, in turn, catalyze the formation of triazolide 4, albeit at a substantially lower rate than that observed by copper catalyst 3. Therefore, it is best to use nonprotic solvents and azides to observe the highest difference in rate between the catalyzed and noncatalyzed experiments.

    • Although complexation of NHCs to transition metals is strongly governed by s-donation, recent investigations have shown that p-backbonding can account for as much as 30% of the overall bonding character.
