The electrochemical reduction of 2-(2,2-dibromovinyl)naphthalene in a DMF solution (Pt cathode) yields selectively 2-ethynylnaphthalene or 2-(bromoethynyl)naphthalene in high yields, depending on the electrolysis conditions. In particular, by simply changing the working potential and the supporting electrolyte, the reaction can be directed towards the synthesis of the terminal alkyne (Et4NBF4) or the bromoalkyne (NaClO4). This study allowed to establish that 2-(bromoethynyl)naphthalene can be converted into 2-ethynylnaphthalene by cathodic reduction.

The electrochemical reduction at −30 °C of 2,6-dichlorobenzaldehyde (1a), benzaldehyde (1b), and terephthalaldehyde (2) in tetrahydrofuran with tetrabutylammonium perchlorate as supporting electrolyte, under an argon atmosphere and in the presence of fluorene or indene, gives carbinols resulting from the addition of fluorene or indene and requires only a catalytic amount of electricity. The chain reaction is initiated by proton abstraction from fluorene or indene by a base electrogenerated by reduction of the aldehyde and the propagation involves the addition of the carbanion to the aldehyde followed by regeneration of the nucleophile by proton transfer from the proton donor to the alkoxide anion (base-catalyzed addition). The voltammetric behavior of the aldehydes in the absence and in the presence of fluorene or indene is also presented. Key words: electrochemical reduction, aromatic aldehydes, addition of fluorene (indene), base catalysis, chain reaction.
