Free radicle substitution

WebThe free-radical substitution reaction consists of three steps: Initiation step. In the initiation step the Cl-Cl or Br-Br is broken by energy from the UV light; This produces two radicals in a homolytic fission reaction; The first step of the free-radical substitution reaction is the initiation step in which two free radicals are formed by sunlight WebThis is a free radical reaction. NBS stands for N-bromosuccinimide. In the initiating step, the NBS loses the N-bromo atom. leaving behind a succinimidyl radical (S·): NBS → S· + ·Br. It is the S· that removes the magenta hydrogen to form succinimide (SH): S· + C6H5CH2CH2H3 → SH + C6H5CH (·)CH2CH3.
