Readily accessible and easy-to-use phenyliodine(III) dichloride, PhICl(2), has been established as an innovative and superior reagent for the one-electron oxidation of cerium(III) complexes, comprising amide, amidinate, and cyclopentadienyl derivatives. Its use allowed the successful synthesis and structural characterization of the first members of three(More)
Synthetic routes leading to two series of (eta(8)-cyclooctatetraenyl)lanthanide(III) scorpionate "mixed sandwich" complexes are reported. The early lanthanide derivatives (COT)Ln(Tp) (Ln = Ce (1), Pr (2), Nd (3), Sm (4)) and (COT)Ln(Tp(Me2)) (Ln = Ce (5), Pr (6), Nd (7), Sm (8)) (COT = eta(8)-cyclooctatetraenyl, Tp = hydrotris(pyrazolyl)borate, Tp(Me2) =(More)
The equimolar reaction of Ce(hfac)4 (1) (hfac = 1,1,1,5,5,5hexafluoropentanedionato) with p-tBu-calix[4](OMe)2(OH)2 in toluene gave the new cerium(IV) calix[4]arene complex {p-tBu-calix[4](OMe)2(O)2}Ce(hfac)2 (2). The single-crystal X-ray structure shows the cone geometry of the calixarene ligand with the methoxy groups coordinated to the cerium; it shows(More)
