2013年2月8日 · When alkenes are treated with hydrohalic acids (HCl, HBr, or HI) they form alkyl halides. This is sometimes called hydrohalogenation of alkenes since it results in the addition …

In this tutorial we’ll look at something very different from our typical mechanisms. Here we’ll talk about radical hydrohalogenation. This is one of the few reactions that gives us an anti …

2013年4月12日 · Free Radical Addition Of HBr To Alkenes Leads To “Anti-Markovnikov” Products. As discussed previously, alkenes normally react with HBr to give products of …

2024年8月22日 · We herein report radical hydroazidation and hydrohalogenation of mono-, di- and trisubstituted alkenes through iron catalysis. The alkene moiety that often occurs as a …

2024年12月12日 · As a powerful alternative to the classical thiol–ene reaction, this protocol features exclusive Markovnikov selectivity, good functional group tolerance and broad …

Free radical addition of HBr to alkenes forms the anti-Markovnikov product. This regiochemistry is explained by the stability of radical intermediate.

2025年1月2日 · Here we report a photocatalytic anti-Markovnikov hydro- and deuterochlorination of unsaturated hydrocarbons enabling access to diverse alkyl and alkenyl chlorides regio- and …

2013年5月24日 · Addition of Hydrogen Halides To Alkynes (Once) – Hydrohalogenation. The three major examples in this category are the reaction of hydrohalic acids (H-Cl, H-Br, and H-I) …

2015年10月13日 · An anti-Markovnikov halogenation is the free-radical addition of hydrogen bromide to an alkene. In the Markovnikov addition of HBr to propene, the H adds to the C …

2024年2月1日 · We demonstrate hydrohalogenation of aliphatic alkenes with collidine·HX salts through dual photoredox/cobalt catalysis. The dual catalysis enables conversion of a proton …
