Table VI. Effect of tert-Butyl Alcohol on Hydrogen Atom Transfer from Tetralin Hydroperoxide to Cumyl Peroxy Radicals at 30°C.

Hydrogen Atom Transfer from Hydroperoxides to Peroxy Radicals. The reaction of cumylperoxy radicals with Tetralin hydroperoxide (Reaction 10) can be studied at hydroperoxide concentrations below those required to reduce the oxidation rate to its limiting value. The rate of oxidation of cumene alone can be represented by ... 

Table V presents a list of estimated enthalpies and half lives for molecular H-atom transfer (disproportionation) from tetralin to a number of unsaturated molecules. At 450°C, and even at 400°C, many structures will undergo rapid molecular disproportionation with tetralin. Approximate relative rates at 400°C for H-atom donation by molecular disproportionation for selected hydrogen donors are estimated below (sources for thermochemistry are given in footnote 1 of Table IV) ...
