title: Easy access to N,N-bis(but-3-enyl)-, N-allyl-N-(but-3-enyl)-, and N-(but-3-ynyl)-N-(but-3-enyl)-amines.
abstract: N,N-Bis(but-3-enyl)amines 5a-i were prepared in overall 74% yield from 1-(triphenylphosphoroylideneaminoalkyl)benzotriazole using an aza-Wittig reaction with aldehydes followed by a double Grignard reaction with allylmagnesium bromide. Use of vinyl or 1-propynylmagnesium bromide and allylmagnesium bromide in a sequential fashion also formed the expected doubly unsaturated amines 9a,b and 12, respectively.
