N-Haloimides (1 -5) are used in two types of radical chain reactions: (i) the selective Ziegler bromination of allylic and benzylic positions [1], which are bromine atom chain reactions [2] and (ii) imidyl radical [3, 4] chain reactions like substitutions and especially additions to double bonds [5,
