Beschreibungen/Notizen

• Palladium(II)‐induced selective B(4)−H activation of an o‐carboranylthioamide has been developed. A tetranuclear palladium(II) complex has been obtained in high yield with excellent regioselectivity. DFT calculations have confirmed that the B(4)‐borometalate is lower in energy than the corresponding B(3)‐borometalate. The product proved to be a good precursor for target mononuclear or trinuclear B(4)−H activated complexes. Site‐specific palladation: A carborane derivative has been regioselectively palladated at its B(4) position by reaction with [PdCl2(CH3CN)2]. The resulting tetranuclear complex serves as a starting material for other Pd complexes by treating it with nucleophiles (see graphic).
