The electrochemical preparation of nanostructured titanium clusters is possible by using a titanium sacrificial anode as the metal source and tetrabutylammonium bromide in THF as the electrolyte and stabilizer. Transmission electron microscopy shows the presence of spherical 3.0‐nm‐sized particles. THF solutions of these Ti clusters induce olefin‐forming McMurry‐type coupling of aldehydes and ketones.
