Abstract
The rearrangement reactions of acetylenic ammonium ylides are not inhibited by the steric requirements of the bicyclic systems of (7a) and (10a); accordingly a non-concerted mechanism analogous to (1)→(2)→(3) is proposed for these reactions, rather than the [2,3] concerted sigmatropic mechanism.Keywords
