  Utility of the 1,3,4,6,7,8-Hexahydro-2H-pyrimido[1,2-a]pyrimidinato Ligand, (hpp)⁻, in Stabilizing Uranium Metallocene Mono-Alkyl and “Tuck-in” Complexes

  摘要：

  Monoalkyl uranium chemistry has been probed by reacting the metallocene chloride complex (C5Me5)(2)(hpp)UCl, 1, (hpp)(-) = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidinato, with alkyl lithium reagents. Complex I reacts with LiMe, LiC equivalent to CPh, LiPh, and LiEt to generate (C5Me5)(2)(hpp)UMe, 2, (C5Me5),(hpp)U(C equivalent to CPh), 3, (C5Me5)(2)(hpp)UPh, 4, and (C5Me5)(2)(hpp)UEt, 5, respectively. Complexes 2-5 react with Cul to form the iodide complex (C5Me5)(7)(hpp)UI, 6, and methane, phenylacetylene, benzene, and ethane, respectively. Attempts to make a neopentyl analogue of 2-5 from the reaction of 1 with neopentyllithium yielded the "tuck-in" complex (C5Me5)(eta(5):eta(1)-C5Me4CH2)(hpp)U, 7. Complex 7 can also be synthesized by heating 5 to 70 degrees C in a reaction that forms ethane as a byproduct.
