Mechanisms of the Catalytic Hydrochlorination of Acetylene: Active Sites, Isotope Effects, and Stereoselectivity

The mechanisms of acetylene vapour-phase hydrochlorination over chloro complexes of noble metals were reviewed. The nature of the active sites of heterogeneous catalysts, isotope effects of HCl/DCl, stereochemistry of reaction products, possible stepwise mechanisms, and mechanisms of individual steps were considered.
