WebNov 25, 2013 · For benzylic bromination, hopefully imagining the mechanism will be straightforward: after initiation (by heat or light), bromine radical then breaks the C-H bond (forming the benzylic radical) [ propagation step #1] and the benzylic radical attacks Br 2 to re-generate bromine radical [ propagation step #2 ]. WebWhen two radicals react, they start sharing the unpaired electrons and form a new σ bond. This is the termination step which ends the chain of propagation steps: The termination is not restricted to the reaction of specific radicals. Any two radicals reacting to form neutral species represent a termination reaction. pickering appliance parts pickering on https://jirehcharters.com
