## Abstract It has been shown by ESR spectroscopy that the title reaction involves abstraction of hydrogen from the phosphite, since at −10°C the reaction has a kinetic deuterium isotope effect, k~H~/k~D~, or ∼3. The rate constant for hydrogen abstraction is __c__. 2 × 10^4^ M^−1^ s^−1^. There is n

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.
Tert-butoxyl radicals react with indole and methyl substituted derivatives by hydrogen abstraction. For those compounds which are unsubstituted at the N-atom, hydrogen abstraction takes place almost exclusively at the N-H bond. The reactivity of these compounds correlates with their donor electron c
