چکیده انگلیسی
Acetylene undergoes hydrochlorination by gaseous HCl in the absence of a solvent on the surface of pre-ground of K2PtCl4 powder. In the DCl atmosphere, trans-d-vinyl chloride is formed. The catalytic reaction proceeds on the active sites, which are lattice defects in the form of π-acetylene complexes generated by mechanical pre-activation of K2PtCl4 salt under acetylene. The limiting step of the reaction is acetylene chloroplatination. It involves a π-acetylene complex and HCl molecule, producing a new π-acetylene platinum(II) complex and intermediate β-chlorovinyl Pt(II) derivative. The protonolysis of the latter species results in vinyl chloride formation.
