WebThe term “rearrangement” is used to describe two different types of organic chemical reactions. A rearrangement may involve the one -step migration of an H atom or of a larger molecular fragment within a relatively short lived intermediate. On the other hand, a rearrangement may be a multi-step reaction that includes the migration of an H ...
