The lanthanide aryloxides Ln(OAr)₃(THF)₂ (Ar = Ar¹ = 2,6-^tBu₂-4-MeC₆H₂, Ln = Yb (1), Y (2); Ar = Ar² = 2,6-ⁱPr₂C₆H₃, Ln = Y (3); Ar = Ar³ = 2,6-Me₂C₆H₃, Ln = Y (4); Ar = Ar¹, Ln = Sm (5), Nd (6)) could be served as highly efficient catalysts for the hydroboration of aldehydes and ketones with good functional group tolerance and excellent chemoselectivity. Computational studies were carried out to probe a feasible mechanism of the Ln-aryloxides catalyzed hydroboration of aldehydes/ketones.
