✦ Synopsis

The effect of a hydroxy group on the reaction of singlet oxygen with an unsaturated group has been studied for linalol and geraniol, model molecules for hydroxylated polyisoprene. Only some of all the possible reactions actually occur. A hydroxy group in a unit strongly deactivates this unit but has little influence on the reactivity of an adjacent unit.

Carboxylic acids initiate the homolytic decomposition of 6-hydroperoxy-6-hexanelactam to alkoxyl and hydroxyl radicals and the reaction of the aldehyde formed from the alkoxyl with 6-hydroperoxy-6-hexanelactam giving monoamide of adipic acid. Polyamides with carboxylic end-groups are oxidized in a s
