This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reagent, Cp2U(NEt2)2, was formed from a reaction of U(NEt2)4 with cyclopentadiene. The reactive nature of the uranium-nitrogen bonds in the starting tetrakisamide complex was retained by Cp2U(NEt2)2. This compound underwent both acid displacement and insertion type reactions to yield a variety of pseudo-six-coordinate complexes of the formula, Cp2U(chelate)2 where chelate = 02CNEt2, OSCNEt2 r S2CNEt2, C>2CPh, C>2CMe, 02CCMe3, OSCPh, OSCMe, cis-(OCMe)(OCCHMe2)Re(CO)4, cis-(OCMe)2Re(CO)4. The compounds, Cp2U(OSCNEt2)2, Cp2U(S2CNEt2)2, and Cp2U(OSCPh)2 were monomeric, Cp2U(02CCMe3)2, dimeric and Cp2U(02CNEt2)2, polymeric in solution, as determined from molecular weight measurements. The spectroscopic data of the compounds are consistent with the designated chelate coordination of the ligands and a pentahapto bonding mode for the cyclopentadienyl rings. The complexes are considered to have octahedral geometry with the ligands and Cp rings in mutually cis positions. The variable temperature NMR data of Cp2U(OSCNEt2)2, Cp2U(S2CNEt2)2, Cp2U(OSCPh)2, and Cp2U[cis-(OCMe)2Re- (CO)4]2 indicated that metal-centered rearrangement processes were averaging non-equivalent environments of the chelate ligands. The carbamates were also assumed to have restricted rotation about the carbon-nitrogen bonds. The AG^ value for the rearrangement in Cp2U[cis-(OCMe)2Re(CO)4]2 was calculated to be 13.5 ± .5 kcal/mole in toluene and 13.7 ± .4 kcal/mole in CH2C12 at a coalescence temperature of 35°C. The rearrangements in the other complexes were still proceeding rapidly even at the lowest accessible temperatures. The dimeric structure of Cp2U(C^CCMe^)2 was assumed to contain four symmetrically bridging carboxylate ligands as the NMR data only showed one methyl resonance. The reagent, Cp2U(NEt2)2, underwent aminolysis reactions with HNPh2, HNC^H^, HNC^H2Me2 and HNC^Me^(COOEt). The compounds, Cp2U(NEt2)(NPh2) and Cp2U[NC^Me^(COOEt)]2 were isolated in a pure form whereas the other pyrroles gave mixtures of mono- and bis-substituted complexes. Attempts to make dichloro containing compounds of the type C1.2U(NR2)2 from UCl^ and the lithio or potassio salts of amines were not completely successful. Although pure Cl~U[N (C ,H, ..)_]_ was obtained, the other complexes, £ b 11 z ^ C12U[N(SiMe^)2]2 and Cl2U(NEt2)2' were contaminated with the trisamide compounds, C1U(NR2)2* Subsequent reactions with cyclopentadiene did not produce pure Cp2UCl2 but mixtures of Cp2UCl2 and Cp^UCl.
