Under the influence of a primary amine with heat both in the presence and in the absence of alkali dialkylallylammonium salts containing a group of the propargyl type form the imines of α-substituted 4-pentenal.
Base Catalysed Rearrangements involving Ylide Intermediates. Part 1. The Rearrangements of Diallyl- and Allylpropynyl-ammonium Cations

, p. 1436 - 1449 (2007/10/02)
The base catalysed rearrangements of diallylammonium cations and allylpropynylammonium cations are described.In most cases, the major product arises by a symmetry-allowed sigmatropic rearrangement of the intermediate ylide.The minor products can be regarded as being derived by homolysis of the ylide into a radical pair followed by recombination.
Base-catalysed rearrangement of allyl-propynyl ammonium cations and a novel synthetic route to substituted biphenyls
Jemison,Laird,Ollis
, p. 556 - 557 (2007/10/06)
Base-catalysed rearrangement of the salts (I) in aprotic media gives the amines (II) and (III); the amines (II) on heating yield the biphenyl derivatives (V).
