Abstract
A convenient and general method for the preparation of (h5-C5H5)(L)Cu compounds is described and illustrated for compounds with L = (C2H5)3P, (C4H9)4P, (C6H5)3P, (CH3O)3P, and CH3NC. The method involves reaction of the appropriate (LCuI)4 or (LCuBr)4 compound with C5H5Tl. The compounds have all been characterized by analyses, pmr, infrared and mass spectra, and, for L = (C6H5)3P and (C2H5)3P, by X-ray diffraction as pentahaptocyclopentadienyl compounds. The compound (h5-C5H5)(CO)Cu has also been prepared by reaction of CuCl, C5H5Tl, and CO in pentane at 0°. It has a very high CO stretching frequency (2093 cm-1) and decomposes rapidly at room temperature.
