The synthesis of 2-(2′-hydroxy-3′-allylphenyl)-4,4-dimethyl-2-oxazoline, H-Allox (3), and lanthanide tris chelate complexes, mer-Ln(Allox)3 (Ln = La (4), Ce (5), Sm (6), Er (7), and Y (8)), derived from it are reported. A six-coordinate mer geometry without alkene coordination was confirmed in the solid state by x-ray crystallog. for 5 and 7. Variable-temperature NMR experiments suggested that this is the most stable isomer in solution as well, although the inequivalent ligand environments undergo rapid averaging at room temperature for all five complexes. A mechanistic study indicated that this fluxional process is an intramol. six-coordinate rearrangement, but it was not possible to distinguish between a Bailar (trigonal) or Ray-Dutt (rhombic) twist. Kinetic parameters for the fluxional process were determined by line shape anal. for 8 yielding ΔH‡ = 24 ± 2 kJ mol-1 and ΔS‡ = -99 ± 10 J mol-1 K-1. The structural and dynamic features of 4-8 were compared with the related In, Ga, and Al tris(2-oxazolylphenoxides).
