Abstract

The lithiated pyrrolyl ligand, {Li[C₄H₂N(CH ₂NMe₂)₂-2,5]}₂ (1) was synthesized and structurally characterized. Reaction of 1 with YCl₃ in the molar ratio 1:1 in diethyl ether at room temperature afforded a di-yttrium di-lithium tetranuclear complex, {[C₄H₂N(CH₂NMe ₂)₂-2,5]YCl₂(μ-Cl) • Li(OEt ₂)₂}₂ (2) in 87% yield. Compounds 1 and 2 were characterized by NMR spectroscopy and single crystal X-ray crystallography. Compound 1 shows high reactivity for the ring-opening polymerization of ε-caprolactone.
