  摘要：

  Treatment of [Co2(mu-HOCR2'C=CCR2'OH)(CO)6] With an excess of RSH in the presence of HBF4.OEt2 affords [Co2(mu-RSCR2'C=CCR2'SR)(CO)6] (R'= H, R = Et, (n)Bu, (t)Bu, Ph, Bz; R'= Me, R = Et), which undergo substitution with bis(diphenylphosphino)methane (dppm) to give [Co2(mu-RSCR2'C=CCR2'SR)(mu-dppm)(CO)4]. Similar treatment of [MoCo(mu-HOCH2C=CCH2OH)(CO)5Cp] and [Mo2(mu-HOCH2C=CCH2OH)(CO)4Cp2] with EtSH gives [MoCo(mu-EtSCH2C=CCH2SEt)(CO)5-Cp] and [Mo2(mu-EtSCH2C=CCH2SEt)(CO)4Cp2], respectively. Reaction of [Co2(mu-HOCH2C=CCH2-OH)(CO)6] with a small excess of RSH (R=Et or Ph), ca. two equivalents, affords [Co2(mu-HOCH2C=CCH2-SR)(CO)6], while reaction with only one equivalent of EtSH additionally gives an ether-bridged system containing two hexacarbonyldicobalt units, [Co2(CO)6(HOCH2C= CCH2OCH2C=CCH2SEt)-Co2(CO)6]. Treatment of [Co2(mu-HOCH2C=CCH2SEt)(CO)6] with half an equivalent of HBF4.OEt2 affords [Co2(CO)6(EtSCH2C=CCH2OCH2C=CCH2SEt)Co2(CO)6]. Attempted preparation of mixed thioether complexes results in a mixture of products, and a mechanism is proposed for thioether scrambling. The IR, NMR and mass spectra of the new compounds are reported and discussed.
