摘要:
                                Attempts to generate a scandium metallocene oxide using N2O have revealed that N2O undergoes facile insertion into metal carbon bonds of allyl meiallocene complexes to form (RN2O)(-) ligands where R = C3H5. This has been demonstrated in reactions with the tetramethylcyclopentadienyl allyl complexes (C5Me4H)(2)M(eta(3)-C3H5)(M = Sc, Y) and the pentamethylcyclopentadienyl allyl compounds (C5Me5)(2)M(eta(3)-C3H5) (M = Y, Sm, La), which generate the insertion products [(C5Me4H)(2)M(mu-eta(1):eta(2)-ON=NC3H5)](2) (M = Sc, 1; Y, 2) and [(C5Me5)(2)M(mu-eta(1):eta(2)-ON=NC3H5)](2)(M = Y, 3; Sm, 4; La, 5), respectively.
