WebIn the 2nd reaction, the carbocation is rapidly attacked by the nucleophile (Br-) to form 2-bromopropane. Formation of 1-Bromopropane: In the presence of benzoyl peroxide, the addition of HBr to propene involves free radical mechanism in which Br-free radical is obtained by the action of benzoyl peroxide on HBr. WebOrganolithium reagents are industrially prepared by the reaction of an halocarbon with lithium metal, i.e. RÄX + 2 Li Å RÄLi + LiX.[1] A side reaction of this synthesis, especially with alkyl iodides, is the Wurtz reaction, in which an RÄLi species reacts with an RÄX species forming an R-R coupled product.
