Base Catalysed Rearrangements Involving Ylide Intermediates. Part 11. Rearrangements of 3-phenylprop-2-ynylammonium Ylides

The propynylammonium salt (5) reacts with aqueous sodium hydroxide to give the allene (7) and a new ylide (11).The simultaneous formation of (7) and (11) suggests that the apparent sigmatropic rearrangement of the propynyl ylide (6) to the allene (7

Base Catalysed Rearrangements involving Ylide Intermediates. Part 2. The Stevens and Sigmatropyc Rearrangements of Allylic Ammonium Ylides

The base catalysed rearrangements of the quaternary ammonium salts (9) usually gives the sigmatropic rearrangement product (10) rather than the Stevens rearrangement product (11).An earlier claim has been corrected: the corresponding reaction
