摘要：
Al B there for Lu: Boryllithium (THF) 2Li{B(NArCH) 2} (Ar=C 6H 3iPr 2-2,6) reacts with excess AlMe 3 to give dimeric {Me 2Al[B(NArCH) 2]} 2, which readily adds to [LnMe 3] n forming homoleptic Ln[AlMe 3B(NArCH) 2] 3 (Ln=Y, Lu, see picture). The reaction with [LnMe 3] n underlines the high methyl mobility and strong Al-B bonding in heteroleptic {Me 2Al[B(NArCH) 2]} 2, which is also evidenced by NMR spectroscopy.
