Addition of Aldehydes to Activated Double Bonds, VIII1) Addition of Thiophenecarbaldehydes to Activated Double Bonds and Desulfurizing Hydrogenation of the Addition ProductsThiophenecarbaldehydes add smoothly to α,β-unsaturated ketones and nitriles under the catalytic influence of cyanide ions to form γ-diketones (1-5) and γ-oxonitriles (6-9). Subsequent desulfurizing hydrogenation yields aliphatic γ-diketones (10-14) and γ-keto carboxylic acids (15-18).
Notes:
Thiophencarbaldehyde addieren unter dem katalytischen Einfluß von Cyanid-Ionen glatt an α, β-ungesättigte Ketone und Nitrile, wobei γ-Diketone (1-5) und γ-Oxonitrile (6-9) gebildet werden. Durch anschließende entschwefelnde Hydrierung gelangt man zu aliphatischen γ-Diketonen (10-14) und γ-Ketocarbonsäuren (15-18).
