The first organoaluminium compound with an Al-Al bond was reported in 1988 as (((Me 3 Si) 2 CH) 2 Al) 2 (a dialane). They are typically prepared reduction of the dialkylaluminium chlorides by metallic potassium: [6] (R 2 AlCl) 2 + 2 K → R 2 Al-AlR 2 + 2 KCl. Another notable group of alanes are tetraalanes containing four Al(I) centres.
