Resumen:
The reactions of the acetylide trinuclear derivatives [(µ-H)M3(CO)9(CCSiMe3)] (M=Fe, Ru) with the thiols C6H5SH and C6F5SH were carried out. Both reactions lead to the formation of products where cleavage of M-M bonds have occurred. In the case of the iron complex, two products are obtained in the reactions with both thiols: a trinuclear complex of formula [Fe3(CO)9(CCSiMe3)(SR)] (R=C6H5 and C6F5) and a dinuclear compound [Fe2(CO)6(CCSiMe3)(SR) (R=C6H5 and C6F5) which is found as anti and syn isomers in the case of C6H5 and only as the anti isomer in the fluorinated thiol. The reaction with the ruthenium complex under the same conditions gives only decomposition products, but when the reaction with pentafluorothiophenol is carried out in the presence of trimethylamine oxide, total cleavage of M-M bonds takes place to form a mononuclear complex [Ru(CO)3(SC6F5)3]. Spectroscopic and structural characterization of the iron complexes is given. Two isomeric crystal structures were obtained for the trinuclear fluorinated complex. © 2017 Elsevier B.V.
