Addition to electron deficient olefins of α-oxy carbon-centered radicals, generated from cyclic ethers and acetals by the reaction with alkylperoxy- λ3-iodane
Thermal decomposition of 1-tert-butylperoxy-1,2-benziodoxol-3(1H)-one in cyclic ethers and acetals at 50°C generates α-oxy carbon-centered radicals, which undergo an addition reaction with vinyl sulfones and unsaturated esters.
Generation of hydroxyl radicals from 1-hydroxypyridine-2(1H)-thione and their application to organic synthesis
Upon irradiation with visible light N-hydroxypyridine-2-thione 1 gives rise to hydroxyl radicals which can be used in radical chain reactions involving selective hydrogen abstraction as the key-step. Key Words: N-hydroxypyridine-2-thione / hydroxyl radicals
