Chromosomal rearrangements encompass several different classes of events: deletions, duplications, inversions; and translocations. each of these events can be caused by breakage of dna double helices in the genome at two different locations, followed by a rejoining of the broken ends to produce a new chromosomal arrangement of genes, different from the gene order of the chromosomes before they.

An analogous version of the hofmann rearrangement has been reported with sulfonamides. 93 the greater acidity of sulfonamides relative to amides has made this variant more difficult to develop due to competing β-elimination. when traditional hypervalent iodine reagents were used, β-elimination occurred to yield imino-λ 3-iodane 82. however.
