Abstract
| - N,N-Bis(but-3-enyl)amines 5a−i were preparedin overall 74% yield from 1-(triphenylphosphoroylideneaminoalkyl)benzotriazole using an aza-Wittig reaction withaldehydes followed by a double Grignard reaction withallylmagnesium bromide. Use of vinyl or 1-propynylmagnesium bromide and allylmagnesium bromide in a sequentialfashion also formed the expected doubly unsaturated amines9a,b and 12, respectively.
