The syntheses and characterizations of Cp ReCl2(SC3H6S), 1, Cp ReCl3(SCHMe2), 2, and Cp ReCl2(SCHMe2)2, 3, are reported (Cp = C5Me4Et). Complex 2 has been characterized by an X-ray diffraction study, which confirms its mononuclear structure. Reactions of 1, 2, and 3 have been studied and compared with those characterized previously for Cp ReCl2(SC2H4S). For example, the thermal reaction of 1 in toluene at 100 °C, results in the elimination of HCl and formation of a complex with a chelated thiolate/thialdehyde ligand, Cp ReCl(SCH2CH2CH&dbd;S), 5. Complex 5 can also be synthesized at a lower temperature by the reaction of 1 with excess triethylamine. Spectroscopic characteristics and reactivity of 5 are reported. |
