Piano-stool lutetium amido and imido compounds supported by a constrained bis(oxazoline)cyclopentadienyl ligand
Abstract
{BoMCptet}Lu(CH2Ph)2 (1; BoMCptet = MeC(OxMe2 2C5Me4; OxMe2 = 4,4-dimethyl-2-oxazoline) was prepared in 95% yield from the reaction of BoMCptetH and Lu(CH2Ph)3THF3. Compound 1 reacts with 1 or 2 equiv of H2NCH2R (R = C6H5, 1-C10H7) to give the corresponding imido complexes [{BoMCptet}LuNCH2R]2 (R = C6H5 (2a), 1-C10H7 (2b)) or amido complexes {BoMCptet}Lu(NHCH2R)2 (R = C6H5 (3a), 1-C10H7 (3b)). When isolated, the imido species are insoluble in nonprotic organic solvents. Crystallographic characterization reveals dimeric [{BoMCptet}LuNCH2(1-C10H7)]2 in the solid state. The reaction of 1 and NH3B(C6F5)3 affords crystallographically characterized {BoMCptet}Lu{NHB(C6F5)2}C6F5. This species is proposed to form via a transient lutetium imido, which undergoes C6F5 migration to the lutetium center.
