391) is Curtius degradation. You get RNH2.
2) is metal acetylide formation. CuC≡CCu is formed, the hydrogens are released.

39Oho...Q2 is acetylene coupling! lol I missed that..sorry.
49Temperature-programmed reaction (TPR) results for acetylene coupling on the Cu(111) surface along with data obtained at atmospheric pressure using Cu/Al2O3 dispersed catalysts are reported. Comparison of the structure, bonding, and reactivity of acetylene on Cu(111) and Pd(111) indicates that the effectiveness of copper in promoting C-H cleavage is associated with greater rehybridization of the C-C bond with concomitant weakening of the C-H bond.
