Abstract

Highly-reactive U° formed by the reaction of U(C5H5)4 with metallic potassium in benzene reacts with further quantities of U(C5H5)4 according to the equation: {A figure is presented} to give bronze-coloured, paramagnetic tricyclopentadienyluranium(III). The latter can also be prepared in benzene by the reaction: UCl3+3 KC5H5 → U(C5H5)3+3 KCl In tetrahydrofuran the compound can be obtained as an adduct U(C5H5)3·OC4H8, which is converted by reaction with l-nicotine in benzene into the black-brown (C5H5)3U·N2C10H14, and with cyclohexylisonitrile in pentane into the red-brown (C5H5)3U·CNC6H11. The isonitrile complex is the first example of a complex compound of uranium with a uranium-carbon single-bond. The IR and mass spectra prove an analogous molecular structure to Pu(C5H5)3 and Am(C5H5)3 for U(C5H5)3 and confirm the composition of the adducts.
