Treatment of the carbon disulfide adducts FpCS2K and Fp′CS2K [Fp′=(η5-C5H4CH 3)Fe(CO)2] with Cp2ZrCl2 affords the μ-(η1-C: η2-S,S′) dithiocarboxylate complexes FpCS2ZrClCp2 (1) and Fp′CS2ZrClCp2 (2). Both stable products were fully characterized. Metathesis between FpCS2K and Cp2ZrCl(OCMe3) provided FpCS2Zr(OCMe3)Cp2 (3), which was not obtained analytically pure. This product was characterized by comparison of its IR and 1H-, 13C{1H}-NMR spectral data with that for 1 and 2. The iron-zirconium complex FpZr(OCMe3)Cp2 (4) was transformed by one equivalent of CS2 to 3 (75% spectroscopic yield), a reaction that did not occur for FpZrClCp2. An insertion pathway is discussed for incorporating the CS2 into the Fe-Zr bond of FpZr(OCMe3)Cp2.
