The reaction is a simply cycloadditon that takes place via copper(I)
acetylide intermediate between ethyl tetrazolo[1,5-a]pyridine-6-carboxylate and respective ethyl propiolate using catalytic amount of copper (I) acetate (Scheme 1) [11].
Roughly 5% of the ring atoms are precipitated as a mixture of silver
acetylide, silver diacetylide, and silver cyanide.

Although the mechanistic details are not clear, previous experiments by McNulty and coworkers [9,10] showed that silver
acetylide formation plays an important role in the catalytic cycle as well as other intermediates [37].
In order to examine the influence of incorporating a transition metal into a |pi~-conjugated system, we have synthesized |8,9~ a number of unsymmetrical bis(
acetylide) complexes of platinum.
