摘要

Reactions of [Ce-IV(L-OEt)(2)Cl-2] (L-OEt(-)= [Co(eta(5)-C5H5){P(O)(OEt)(2)}(3)](-)) and [Ce-2(IV) (mu-O){N((Pr2PO)-P-i)(2)}(4)Cl-2] with PhIO afford the lambda(3)-iodane complexes [Ce-IV(L-OEt)(2){OI(Cl) Ph}(2)] and [CeIV2 {N(Pri(2)PO)(2)}(3){OI(Cl) Ph}], respectively, whereas that between [CeIV(L-OEt)(2)Cl-2] and PhIO2 or excess PhIO yields the lambda(5)-iodane adduct [CeIV(L-OEt)(2){OI(O) ClPh}(2)]. The crystal structures of the Ce-IV lambda(3)-and lambda(5)-iodane complexes have been determined and their oxo transfer reactivities have been investigated.
