Anti-Markovnikov hydrohalogenation haloalkanes cost-free radicals mediated addition of hydrohalic acids
From the presence of an suitable photosensitiser, like methylene blue and light, alkenes can undertake response with reactive oxygen species created via the photosensitiser, like hydroxyl radicals, singlet oxygen or superoxide ion. Reactions on the fired up sensitizer can involve electron or hydrogen transfer, ordinarily with a cutting down substrate (Form I response) or interaction with oxygen this (Style II reaction).
