摘要:
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 degreesC, results in the elimination of HCl and formation of a complex with a chelated thiolate/thialdehyde ligand, Cp"ReCl(SCH2CH2CH=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.
