Table 2. Relevant Processes of Cu(I) Adduct Formation/Dissociation Investigated by DFT.

#	process
1	Cu(I)(CO) formation	ZCu(I) + CO → ZCu(I)(CO)
2	Cu(I)(CO)2 formation	ZCu(I)(CO) + CO → ZCu(I)(CO)2
3	Cu(I)(NH3) formation	ZCu(I) + NH3 → ZCu(I)(NH3)
4	Cu(I)(CO)(NH3) formation	ZCu(I)(NH3) + CO → ZCu(I)(CO)(NH3)
