WebAlkenes can react with different types of chemicals during addition reactions. Alkene + hydrogen → alkane. This is called hydrogenation, and it needs a catalyst. For example: Web1 day ago · The redox-neutral dialkylation of alkenes with alkyl electrophiles and alkylmetallic nucleophiles was pioneered by the Oshima 17 and Kambe group 18 and, since then, have been extensively investigated by the Engle, 19, 20 Giri, 21 and Morken 22 group et al. using nickel catalysts (Scheme 1 B). However, these protocols heavily rely on pre …
