  • Amine synthesis by amide reduction

    A triruthenium cluster catalyzes the reaction of secondary amides with hydrosilanes, yielding a mixture of secondary amines, tertiary amines, and silyl enamines. Production of secondary amines with complete selectivity is achieved by the use of higher concentration of the catalyst and bifunctional hydrosilanes such as 1,1,3,3-tetramethyldisiloxane followed by acidic workup.
