摘要

Reaction of homoleptic yttrium tris-alkyl complex YR3 (R=CH2C3H4NMe2-o) with 1 equivalent of amine bis(phenol)s LH2 (L=Me2NCH2CH2N(CH2-(2-O-C6H2-Butt2-3,5))2) afforded the solvent-free yttrium alkyl complex LYR (1), which has been characterized with elemental analysis, 1H NMR and IR spectra, and structural determination. The coordination geometry around the center metal atom can be best de-scribed as a distorted octahedron. It was found that complex 1 can be used as an efficient catalyst for the Tishchenko reaction.
