Alkynylation of Aldehydes Initiated by Cathodic Reduction

Alkynylation of aldehydes initiated by cathodic reduction was performed. The cathodic alkynylation required only a semi-catalytic amount of electricity to consume the starting material completely. Cyclic voltammetry and some control experiments suggest that the electron-generated base derived from the cathodic reduction of benzaldehyde promotes alkynylation.

Automated summary

In this study, the alkynylation of aldehydes initiated by cathodic reduction was investigated. It was found that only a small amount of catalytic current was needed to completely consume the starting material. Cyclic voltammetry and control experiments suggested that the electron-generated base from the cathodic reduction of benzaldehyde promoted the alkynylation reaction.
