SYNTHESIS AND CHARACTERIZATION OF PHTHALO YL BRIDGED IRON-SULFUR COMPLEXES [(MU-RS)FE-2(CO)(6)](2)(MU-OCC6H4CO-MU)

The in situ reaction of the complex salts [(mu-CO)(mu-RS)Fe-2(CO)(6)]E T(3)NH derived from Fe-3(CO)(12), RSH and Et(3)N with p-, or m-phthalo yl chloride in THF at room temperature afforded six novel phthaloyl br idged iron-sulfur complexes [(mu-RS)Fe-2(CO)(6)](2) (mu-p-OCC6H4CO-p-m u) (R = Et, n-BU, t-Bu) and [(mu-RS)Fe-2(CO)(6)](2)(mu-m-OCC6H4CO-m-mu ) (R = n-Pr, n-Bu, t-Bu). These new complexes were characterized by el emental analysis, IR and H-1 NMR spectroscopies and the reaction cours e was discussed. In addition, a new synthetic route to p-phthaloyl chl oride has been developed.
