The sigmatropic rearrangements of 2-oxyanilinium ylides
Abstract
The [1,4] sigmatropic rearrangement of the anilinium ylides derived from the salts (1) is an intramolecular process, (1)→(2); the N-allyl ylide (8) reacts, in addition, by a sequence of [2,3] and [3,3] sigmatropic rearrangements to give the allyl phenol (10).
