The k11 rate constants for the reaction between diphenylcarbonyl oxide and seven olefins were determined by the method of pulsed photolysis. The k11 values depend on the natures of olefins and solvents and change from 11 ± 3 for styrene in acetonitrile to (6.0 ± 0.6) × 104 dm3 mol-1 s-1 for 1,4-dichlorobutene-2 in n-decane. The rate constants for symmetrical olefins such as 1,4-dichlorobutene-2, stylbene, and cis-1,2-dichloroethylene are 1-2 orders of magnitude larger than for styrene, hexene-1, n-butyl vinyl ether, and 2-bromopropene-1. Solvent effects on k11 are considered in terms of the Winstein-Gruenwald equation. An increase in solvent polarity stabilizes carbonyl oxide and decreases the rate constant for the reaction. The products formed in the reaction between Ph2COO and styrene were studied. A possible mechanism of the reaction is discussed.

The oxidation of 1,4-dichloro-2-butene by aqueous sodium hypochlorite was studied.A sharp increase in the reaction rate was found in the presence of phase transfer catalysts and surfactants.The involvement of oxygen as a cooxidant and the effect of surfactants on the absorption of atmospheric oxygen by the reaction system were demonstrated.
