| Abstract: | The activities of two catalytic systems toward the exchange reaction of CCl4 with hydrocarbons are compared: a copper chloride complex with DMF and polycopperphenylsiloxane (PCPS). PCPS is a very stable
catalyst. It completely preserves its catalytic activity after six catalytic cycles. Competitive reactions with the pairs
of hydrocarbons suggested a radical-chain mechanism for the title reaction for both catalysts. |
