Homoleptic Lanthanide Amides as Homogeneous Catalysts for the Tishchenko Reaction.

Known for about 25 years, the bis(trimethylsilyl)amides of Group 3 metals and lanthanides, M[N(SiMe ) ] , are well suited as highly efficient catalysts for the dimerization of aldehydes [Tishchenko reaction, Eq. (1)].
