ELECTROCHEMICAL REDUCTIVE AMINATION. II. AMINATION OF ALIPHATIC ALDEHYDES WITH PRIMARY AMINES

The formation of a secondary amine by the electrolysis of an aqueous solution containing an aldehyde and a primary amine was studied.The formation of the secondary amines passes through the intermediate stage of an aldimine.The highest yield of secondary amine is attained at a molar ratio of primary amine to aldehyde of 1.2:1.As electrode material lead, cadmium, zinc, and copper may be used.As supporting electrolyte a phosphate buffer with a pH close to the pKa of the primary amine is recommended.By the method developed 32 amines with various structures were synthesized.

ELECTROCHEMICAL REDUCTIVE AMINATION. I. AMINATION OF ALIPHATIC KETONES BY PRIMARY AMINES

The reductive amination of aliphatic ketones in aqueous solutions of primary amines was realized by an electrochemical method.The best yields of the secondary amines were obtained at lead and cadmium cathodes in an aqueous electrolytic solution at pH 11-12.Elongation and branching in the carbon chain of the radicals both of the ketone and of the primary amine lead to a reduction in the yield of the secondary amine.The yield of the secondary amine is mainly determined by the rate of the chemical reaction leading to the formation of the azomethine compound, preceding the electrochemical reduction stage.

Organoboranes for synthesis. Reaction of organoboranes with representative organic azides. A general stereospecific synthesis of secondary amines and N-substituted aziridines

Reaction of trialkylboranes with organic azides in refluxing xylene, followed by hydrolysis, leads to good yields of secondary amines. This reaction is highly dependent on the steric effects around both boron and the azide moiety. The reaction becomes much slower when the steric bulk of one of the reagents is increased and fails when both are hindered. The dialkylchloroboranes are more reactive than trialkylboranes and provide better yields of the desired secondary amines with a11 azides tested. The alkyldichloroboranes react with organic azides at temperatures between room temperature and 60°C and produce excellent yields of secondary amines. Furthermore, the stereochemistry of the original carbon-boron bond is retained. The mechanism of these reactions is discussed and the reaction applied to the synthesis of N-alkyl- and N-arylaziridines.

Process for the alkylation of secondary aliphatic amines in the presence of an amide of a transition metal

A process for the alkylation of secondary aliphatic amines is provided which consists of reacting a secondary aliphatic amine with at least one hydrogen on the alpha carbon atom of the amino group with an olefine in the presence of an amide of a transition metal.
