摘要：

Alkyl complexes of uranium supported by ferrocene diamide ligands are described along with the corresponding cationic species. Synthesis of uranium dialkyl compounds fc(NSiBuMe2)(2)UR2 [R = Np (neo-pentyl), Bz (benzyl)] was accomplished by salt metathesis between fc(NSiBuMe2)(2)UI2(THF) and neo-pentyl lithium or benzyl potassium. Protonation of one alkyl ligand led to the isolation of a cationic uranium alkyl complex. DFT calculations and X-ray crystallography data support the existence of a donor-acceptor, weak interaction between iron and uranium.
