Ruthenium-Catalyzed Hydrogenation of Alkynylstannanes with Migration of the Stannyl Group

Ruthenium-Catalyzed Hydrogenation of Alkynylstannanes with Migration of the Stannyl Group

Molecular hydrogen adds to aliphatic and aromatic alkynylstannanes in the presence of a ruthenium catalyst, pushing the stannyl group to the adjacent carbon atom to give α-substituted vinylstannanes. This is the first achievement of hydrogenation of alkynylstannanes, which is applicable also to the...

Zusammenfassung:Molecular hydrogen adds to aliphatic and aromatic alkynylstannanes in the presence of a ruthenium catalyst, pushing the stannyl group to the adjacent carbon atom to give α-substituted vinylstannanes. This is the first achievement of hydrogenation of alkynylstannanes, which is applicable also to the deuteration affording precursors for an important class of deuterium-labeled compounds.
