Mitchenko R. Activation of triple C-C bond by chloro platinum(II) complexes

The thesis are dealing with developing of synthetic methods and studying of reactivity of chloro Pt(IV) monovinyl derivativies, as well as searching for effects of mechanoactivation of chloro Pt(II) complexes towards heterogeneous catalysis of acetylene hydrochlorination, determination of the nature of active sites of a catalyst and mechanism of catalytic reaction. A new catalytic reaction of terminal alkynes chloroplatination by chloro Pt(II) complexes цas found out. Method for synthesis of new class of monovinyl derivativies of chloro Pt(IV) complexes was elaborated. Catalysis of acetylene hydrochlorination by gaseous HCl at room temperature on the surface of dry K2PtCl4 salt mechanically pre-activated under acetylene atmosphere was found. The reaction kinetic was studied and mechanism of acetylene heterogeneous catalytic hydrochlorination of on the surface of mechanoactivated K2PtCl4 salt was proposed.
