A heterogeneous catalyst for the hydrochlorination of acetylene using gaseous HCl was obtained by prior mechanical activation of K2PdCl4 powder in an atmosphere of acetylene or propylene. Active sites are formed during the mechanical treatment in the surface layers of the catalyst, which are Pd(II) complexes with a coordination vacancy.

Notes
Ligand exchange is usually accomplished through a dissociative mechanism but the dissociation of ligands is unlikely in the absence of salvation [11].
