Abstract

Propargyl bromide was converted to the resp. allenylmagnesium bromide and added to nitro compds. to give N-aryl-N propargylhydroxylamines and N-alkyl-N-propargylhydroxylamines RN(CH2C≡CH)OH I (R = Ph, 4-ClC6H4, 1-naphthyl, hexyl, cyclohexyl, 4-MeC6H4CH2CH2 etc.) in the presence of LiAlH4 and Pd/C. I are not further reduced to give, e.g., N-propargylanilines.
