the amine, and is also influenced by the nature of the solvent. Primary aliphatic 1,2- or 1,3-diamines yield cyclic aminals which are imidazolidine (8a) and hexahydropyrimidine (8b) derivatives. Reactions of these aminals with Grignard reagents, and with cyanide anion as nucleophiles, are also described.
