The lithiated pyrrolyl ligand, {Li[C4H2N(CH2NMe2)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(CH2NMe2)2-2,5]YCl2(μ-Cl) · Li(OEt2)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.
