Abstract (en)
[origin: WO2013017281A1] The invention relates to chelate-stabilized homoleptic triaryl compounds based on phenylphosphoranes, to methods for preparing same and to the use thereof as catalysts. According to the invention, the object is achieved by homoleptic rare earth triaryl complexes of the general formula (1), where SE = Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb or Lu; X = O, CRR'; R1, R2 = phenyl; R, R' = mutually independently H, alkyl with n = 10 C atoms, phenyl or trimethylsilyl.
