The thermalrearrangements of the (2′E)-penta-2′,4′-dienylammonioamidates (13) give products (14) and (15) that are formally derived from [1,2] and [5,2] rearrangements and, in some cases, the product (16) of a [3,2] rearrangement. The products (14) and (15) are formed by a radical mechanism in which (a) radical recombination to give the products (14) and (15) competes with recombination to give the
