Reactions of organomagnesium compounds with aliphatic azomethines and with hexamethylenetetramine.
I. Vera Evdokimoff
Gazz. Chim. ital. 77, 318-326 (1947) CA 42:2586c (1948)
Summary: Amphetamine via the grignard rxn of benzyl magnesium chloride with acetaldehyde-methylamine imine.

CH3-CHO + H2N-CH3 --> CH3-CH=N-CH3 - H2O

Ph-CH2-Mg-Cl + CH3-CH=N-CH3 --> Ph-CH2-CH-(N-CH3)-CH3

1. The Grignard Reaction with Schiff Bases
Robert Bruce Moffett & Willard M. Hoehn
J. Am. Chem. Soc., Vol. 69, p. 1792-1794 (1947)

Summary: The reaction of benzyl-magnesium chloride on the Schiff bases from substituted benzaldehydes and primary amines has been found to be a suitable method for the preparation of 1,2-diphenyl-ethylamines. 19 new secondary amines have been prepared by this reaction.

2. The Reaction of Grignard Reagents with Schiff Bases
K. N. Campbell, C. H. Helbing, M. P. Florkowski & B. K. Campbell
J. Am. Chem. Soc., Vol. 70, p3868-70 (1948)

Summary: Several new amines have been prepared by the action of Grignard reagents on Schiff bases of the type: Ph-CH=N-R. The effect of structure of the aldimine and of the Grignard reagent on the yield of amine has been determined.
