Abstract:A series of nitrile-coordinating complexes [Cp*Fe(mu-SEt)RCN](2)[PF6](2) (1, R = alkyl, aryl, vinyl, amine) have been obtained by the reaction of [Cp*Fe(mu-SEt)MeCN](2)[PF6](2) (1a) with various nitriles in acetone. Complexes 1 can realize the hydration of a nitrile ligand under ambient conditions. Complexes [Cp*Fe(mu-SEt)(2)(rho-eta(1):eta(1)-NH(O)CR)FeCp*][PF6] (2) were successfully isolated as intermediates during the hydration process, with 2b and 2e (R = CH2=CH and Et2N) being characterized by spectrometry and X-ray crystallography. Treatment of 2 with HBF4 center dot Et2O in the presence of nitriles released corresponding amides 3. At the same time, the structural features of the [Fe2S2] scaffold were retained. These results confirmed that the hydration of nitriles was realized by cooperative interaction on diiron centers.
