Very nice effort to reproduce their chemistry. The main issue I see is that they say that any oxygen present is detrimental, so purging the reaction
with nitrogen would be helpful. A simple sealed glass pressure tube should be able to handle those pressures, or a microwave type vial with a crimp
top. But the chemistry looks possible, although it would not surprise me if there was not a small amount of palladium in the copper (I) iodide,
which could be helping the reaction as well. That would not be the first time that trace heavy metals assisted a reaction.
