2-Propynylamines from 1,1-Dibromo-1-alkenes Easily accessible 1,1-dibromo-1-alkenes 1 react with primary or secondary amines in a complex series of reactions to give directly N-substituted or N,N-disubstituted (1-Alkyl-1-aryl-2-propynyl)- amines 5 in useful yields. This simple method avoids the isolation of the intermediates (bromoacetylenes or bromoallenes) and makes a series of 2-propynylamines with an acetylenic hydrogen available.
