Comprehensive Summary

Herein, we describe the synthesis of a carborane-supported octanuclear palladacycle complex, Pd8(o-C2B10H10CS2CH3)4Cl4(CH3CN)4 (complex 1), with B(3)–H activations on o-carborane ligand. The substitution reaction of 1 has been explored, and three of its substituted complexes Pd8(o-C2B10H10CS2CH3)4Cl4(L)4 (L = tBuNC, 2; L = C5H5N, 3; L = C4H8S, 4) have been synthesized. The m- and p-carborane disubstituted ligands m- and p-C2B10H10(CS2CH3)2 (ligands 5 and 6) as well as their B—H activated carborane complexes [m-C2B10H9(CS2CH3)2PdCl] (7) and [p-C2B10H8(CS2CH3)2][PdCl(tBuNC)]2 (8) have also been synthesized by the similar method. All of these complexes have been characterized, including X-ray single crystal diffraction, NMR spectroscopy, IR spectroscopy and elemental analysis methods. image
