Cleavage of the carbon‐silicon bond in 1‐alkynylsilanes by silver nitrate: Protection of a terminal triple bond in hydrogenation reactions with the trimethylsilyl group

Abstract

Abstract It is possible to reduce non‐terminal triple bonds in poly‐ynes selectively when the terminal triple bonds are previously protected silylation. Desilylation after the reduction can be easily effected with aqueous alcoholic silver nitrate.
