COMPLEXES BISCYCLOPENTADIENYLES DISSYMETRIQUES ET TRISCYCLOPENTADIENYLES MIXTES DE L'URANIUM(IV). U COMME CENTRE DE PSEUDOASYMETRIE
Dormond, A.
, p. 47 - 56 (1983)
Starting from the monocyclopentadienyls U(C5Me4R)X3 (X = Cl or NEt2, R = CH3 or C2H5), the bis-cyclopentadienyl dissymetric complexes U(C5Me4R)CpX2 (Cp = substituted or unsubstituted cyclopentadienyl ligand) and the tris-cyclopentadienyl complexes U(C5Me4R)Cp2Cl are obtained.If the two Cp ligands have a chiral center, a mixture of one racemic and two meso isomers is obtained.In the meso isomers, the uranium atom is a pseudoasymmetric center.
