Abstract: 1,4-dilithiotetraphenylbutadiene was obtained by the reaction of diphenylacetylene with lithium in Et2O and two kinds of f-elements-2,3,4,5-tetraphenyl-cyclopentadiene complexes were prepared by the further reaction of Li(C6H5)C=C(C6H5)(C6H5)C = C(C6H5) Li with LnCl3 in THF. These complexes were identified by elements analyses, IR, NMR, thermal ana-lyses and ESCA. The analyses of hydrolytic products were made by IR, MS and NMR. The tructural formulae of the complexes are as follows:  |
