Cage effect peresters

The next nine chapters, grouped under the subheading of "Initiator Chemistry, are concerned with various aspects of research on topics of current interest dealing with the energetics and detailed mechanisms of radical production. The first chapter in this section summarizes Paul Bartlett s most recent results on photooxidation and the identity of the elusive epoxidation reagent. Other chapters treat MAH reactions, peroxide and perester reactions, cyclic endoperoxides, diazenes, cage effects, and radiation. 

While these qualitative observations substantiate the gross features of the cage scheme, quantitative comparisons are necessary if one is Interested in the effects such as those due to the (variable) intervening molecules on cage reactions. The value of kj, the fundamental rate constant for 0-0 bond homolysls of a nonconcerted perester, is not directly available from any single experiment in condensed media. According to Scheme I and the assumption that k j is the only vlscos-...
