Аннотация:The catalytic activity of linear and network oligomer copperorganosiloxanes immobilized on the surface of Silochrome in a reaction of CCl4addition to olefins was studied. It is likely that the reduction of Cu(II) ions to Cu(I) is a step in the catalytic radical reaction studied. This process also occurs in the absence of reagents at relatively low temperatures. The reaction occurs more readily in linear polycopperorganosiloxanes than in the network oligomers, which is consistent with the catalytic activity. The studied catalytic reaction is characterized by an unusual dependence of the activity of polycopperorganosiloxanes on metal concentration.
