摘要:
Hydrolysis studies of derivatives of molybdocene dichloride in which the two chloride ligands were replaced by 3,5-bis(trifluoromethyl) thiophenol, 3,5-bis(trifluoromethyl) benzyl thiol, and 2,2,2-trifluoroethane thiol ligands confirmed that the electron-withdrawing groups affect the lability of the Mo-S bonds and promote slow generation of the putative biologically active species "Cp2Mo2+"; the trifluoroethane thiol derivative underwent 50% hydrolysis in 14 h in 10% D2O/DMSO-d(6). The structure of molybdocene bis(S-3,5-bis(trifluoromethyl) benzyl thiol) was confirmed by X-ray crystal structure analysis.
