- W2314744529 abstract "The anilide–bis(aryloxide) proligands H3[ONOR] (where H3[ONOR] = 2,6-(3-R1-5-R2-2-hydroxybenzyl)-4-tert-butyl-N-tolyl-aniline; H3[ONOtBu], R1 = tBu, R2 = Me; H3[ONOMe], R1 = Me, R2 = tBu; H3[ONOMe2], R1 = R2 = Me) were synthesized from 2-bromo-5-tert-butyl-isophthalic acid dimethyl ester in three steps in multigram scale. The ligand precursor H3[ONOtBu] was readily doubly and triply deprotonated with alkali metal reagents to generate the related derivatives M2[H(ONOtBu)] and M3[ONOtBu] (M = Li, Na, K). The extent of ligand deprotonation is observed to depend on the choice of deprotonating reagents and solvents. Transmetalation reaction of the trilithium derivative Li3[ONOtBu] with MCl3(THF)3 (M = Cr, V; THF = tetrahydrofuran) afforded [(ONOtBu)CrCl(THF){Li(THF)}] (5) and [(ONOtBu)V(THF)] (6). The vanadium complex 6 reacted readily with 2-butyne, styrene oxide, and mesityl azide, yielding [(ONOtBu)V(η2-MeCCMe)] (7), [(ONOtBu)V(O)] (8), and [(ONOtBu)V(NMes)] (9), respectively. The solid-state structures of H3[ONOtBu] and metal complexes were determined by X-ray crystallography. The [ONOtBu] ligand adopts a u-shaped structure in solution and solid state." @default.
