Abstract

The bimetallic cluster complex Fe2(μ-SnBu2t)2(CO)8, 1, selectively activates the benzylic C-H bond in solvent toluene at reflux conditions to afford the complex Fe2[μ-SnBut(CH2Ph)]2(CO)8, 3, where two of the But groups in 1 have been replaced with benzyl groups. Similarly 1 also activates the benzylic C-H bond in solvent m-xylene to yield complexes Fe2[μ-SnBut(m-CH2PhMe)]2(CO)8, 4, Fe2[μ-SnBut(m-CH2PhMe)][μ-Sn(m-CH2PhMe)2](CO)8, 5, and Fe2[μ-Sn(m-CH2PhMe)2]2(CO)8, 6, where two, three and four of the But groups in 1 have been replaced by m-tolyl groups, respectively. A mechanism based on a radical pathway is proposed for the C-H activation by 1.
