The yields of primary amines from monochloroamine and Grignard reagents prepared from alkyl halides vary greatly with the halogen present in the reagent. For example the yields from n-butyl reagents decrease from an average of 60 per cent with the chloride to about 15 per cent or less with the iodide. The percentage of dialkylmagnesium present in the three n-butyl reagents is about the same being above 65 per cent in each. With di-nbutylmagnesium however prepared from each of the three n-butyl Grignard reagents by the dioxane method the yields of n-butylamine are above 80 per cent
