## Abstract It has been shown by ESR spectroscopy that the title reaction involves abstraction of hydrogen from the phosphite, since at β10Β°C the reaction has a kinetic deuterium isotope effect, k~H~/k~D~, or βΌ3. The rate constant for hydrogen abstraction is __c__. 2 Γ 10^4^ M^β1^ s^β1^. There is n

β¦ Synopsis
Photolytically generated tert-butoxyl radicals react with vinyl-and propenyl ethers by hydrogen abstraction and addition to the double bond; the abstraction/addition ratio and the regioselectivity of addition are interpreted in terms of predominant steric interactions.

The radical trapping technique employing l,l,3,3-tetramethy l-l,3-dihydro-lH-isoindol-2yloxyl as a scavenger has been used to investigate the reaction of t-butoxyl radicals with mixtures of ethyl vinyl ether and methyl methacrylate. Tbe range of identified products includes those from both addition
