摘要：

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.
