Abstract

This paper presents some unusual reactions of lanthanide tris (alkyl) s or lanthanide mono- Cp′(Cp′=(C5Me4) SiMe3) bis (alkyl) s with pyrrolyl ligands, and the η5-or η1-coordination mode of the pyrrolyl ring, as well as CN and CO double bonds insertion into Ln–σ-C moities. N, N, O-tridentate ligand HL1, 2-(2-CH3OC6H3NCH)–C4H3NH, was prepared. Treatment of HL1 with rare-earth metal tris (alkyl) s, Ln (CH2SiMe3) 3 (THF) 2, generated ...
